Also, there is also a post on the definition or explanation of this velocity. You need some basics of orbital mechanics. None of these three equations has the variable Msatellite in them. Around the earth the value of orbital velocity is 7.92 km/sec. Since the escape velocity does not depend upon the angle of projection, hence the escape velocity will be same. Notice the similarity in the equations for [latex] {v}_{\text{orbit}} [/latex] and [latex] {v}_{\text{esc}} [/latex]. When the radius of the orbit is 4 times than that of Earth's radius, then orbital velocity in that orbit is(a) 3.5 km/s (b) 7 km/s, (c) 72 km/s (d) 14 km/s. Value of orbital velocity does not depend on the mass of the satellite. Physical World, Units and Measurements.

Orbital velocity of earth’s satellite near the surface is 7 kms^–1. Orbital velocity of a satellite is the minimum velocity required to the satellite into a given orbit around earth. The satellites orbital speed does not depend on it’s mass for the same reason the acceleration due to gravity does not depend on the mass of the falling object. Medium. Well as from the orbital velocity equation you can see velocity is depending upon inversely distance from centre of Earth, Hence closer to the Earth satellite velocity will be higher and far satellite will be less velocity. Similarly, a satellite placed in an orbit at around 1730 kilometers will need a speed of 25,400 kilometers per hour. Question 8. Prove that a satellite revolving close to the Earth’s surface has orbital velocity approximately 8 km/s. At an altitude of 124 miles (200 kilometers), the required orbital velocity is a little more than 17,000 mph (about 27,400 kph). Orbital velocity is independent of mass of satellite. It does not depend on the direction of projection. According to standard orbital perturbation theory, the time evolution of the satellite's orbital elements ... and inclination, , due to the Earth's oblateness (because does not depend … Get important questions of Gravitation Class 11 with their answers.

C. the orbital radius. Its orbital velocity mainly depends upon. Yes. This will permanently delete All Practiced Questions. Welcome to Sarthaks eConnect: A unique platform where students can interact with teachers/experts/students to get solutions to their queries. ... Orbital Velocity. Factors affecting the orbital velocity of a satellite. The speed of a satellite is dependent on where it is in it's orbit, the semi-major Axis of its orbit and the mass of the object it orbits. A. At a given point P, it is closest from the sun at a distance d1 and has a speed v1. Orbital velocity of an artificial satellite does not depend upon . ... Value of orbital velocity does not depend on the mass of the satellite. At higher altitudes, satellites do not need to be travelling as fast. ANSWER Rp = (6,378.14 + 250) × 1,000 = 6,628,140 m Ra = (6,378.14 + 500) × 1,000 = 6,878,140 m The orbital velocity v of a satellite may depend on its mass m, the distane r from the centre of the earth and acceleration due to gravity g. Obtain an expression for its orbital velocity. The orbital velocity of an artificial satellite in a circular orbit just above the earth's surface is v. For a satellite orbiting at an altitude of half of the earth's radius, the orbital velocity is(a) 32v (b) 32v, In a satellite if the time of revolution is T, then K.E. Next: Effect of ... mean orbital angular velocity. By definition, a geosynchronous satellite orbits the earth in a perfect circle, maintaining the same distance above the surface of the earth. planet, moon, artificial satellite, spacecraft, or star) is the speed at which it orbits around either the barycenter or, if one object is much more more massive than the other bodies in the system, its speed relative to the center of mass of the most massive body.. D. the mass of satellite. The period of motion T of an artificial satellite of earth at a distance h above the surface of the earth is given by, where, R e = radius of the earth. A. Physics. v orbit = G M E r. 13.7 Consistent with what we saw in Equation 13.2 and Equation 13.6, m does not appear in Equation 13.7. Effect of terrestrial oblateness on artificial satellite orbits. Which one of the following statements regarding artificial satellite of the earth is incorrect. The nearer to Earth, the faster the required orbital velocity. Assertion : The speed of revolution of an artificial satellite revolving very near the earth is \[8\,km{{s}^{-1}}\]. Orbital velocity of an artificial satellite does not depend upon . An artificial satellite is revolving round the earth in a circular orbit. Escape velocity of a particle from the surface of the earth depends on the speed with which it is fired III. B. the radius of earth. Books. ... then the orbital velocity mainly depends on. The time period of a satellite does not depend on the radius of the orbit. Open App Continue with Mobile Browser. Does the comet have a constant (a) linear speed, (b) angular speed, (c) angular momentum, its velocity is half the escape velocity. An artificial satellite is revolving round the earth in a circular orbit. A solid sphere and a hollow sphere are heated the same temperature. For example, a satellite which is placed in an orbit at altitude of 200 kilometers will need an orbital velocity of approximately 29,000 kilometer per hour. Velocity of satellite closer to the Earth The time period of a satellite does not depend onthe radius of the orbit IV. These important questions of gravitation will play significant role in clearing concepts of Physics class 11 as well as in revision of 12th students. The orbital velocity of a satellite does not depend upon the mass of the planet around which it orbits. The orbital velocity of a satellite increases with the radius of the orbit II. D. The planet mass : The orbital velocity of a satellite is directly proportional to square root of the mass of the planet at constant radius of the orbit . Doubtnut is better on App. When the radius of orbit is 4 times that of earth’s radius, If the height of a satellite from the earth is negligible in comparison of the radius of the earth R, the orbital velocity of the satellite is. The orbital radius only. Something you should already be comfortable with. If a satellite is revolving very close to the surface of earth, then its orbital velocity does not depend upon. Around the earth the value of orbital velocity is 7.92 km/sec.
