To view Explanation, Please buy any of the course from below. 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 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. B. Consistent with what we saw in and , m does not appear in .The value of g, the escape velocity, and orbital velocity depend only upon the distance from the center of the planet, and not upon the mass of the object being acted upon. Value of orbital velocity does not depend on the mass of the satellite. 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.

Orbital velocity of an artificial satellite does not depend upon . Effect of terrestrial oblateness on artificial satellite orbits. 10. Question 8. ... From the above formula, it is clear that escape velocity does not depend upon the test mass (m). T or F: 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 does not depend upon the mass of the planet around which it orbits. D. the mass of satellite. Next: Effect of ... mean orbital angular velocity. A solid sphere and a hollow sphere are heated the same temperature. By definition, a geosynchronous satellite orbits the earth in a perfect circle, maintaining the same distance above the surface of the earth. Paiye sabhi sawalon ka Video solution sirf photo khinch kar. V orbital = [(GM)/r] 1/2. An artificial satellite is revolving round the earth in a circular orbit. Since the escape velocity does not depend upon the angle of projection, hence the escape velocity will be same. As escape velocity Vesc = √ (2gR).and the value of ‘g’ depends upon the height of location from where body is projected. Students (upto class 10+2) preparing for All Government Exams, CBSE Board Exam, ICSE Board Exam, State Board Exam, JEE (Mains+Advance) and NEET can ask questions from any subject and get quick answers by subject teachers/ experts/mentors/students. Factors affecting the orbital velocity of a satellite. Assertion : The speed of revolution of an artificial satellite revolving very near the earth is \[8\,km{{s}^{-1}}\]. The value of g, the escape velocity, and orbital velocity depend only upon the distance from the center of the planet, and not upon the mass of the object being acted upon. 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. This will permanently delete All Practiced Questions. 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.. Around the earth the value of orbital velocity is 7.92 km/sec. The time period of a satellite does not depend onthe radius of the orbit IV. At an altitude of 124 miles (200 kilometers), the required orbital velocity is a little more than 17,000 mph (about 27,400 kph). Around the earth the value of orbital velocity is 7.92 km/sec. Orbital velocity is independent of 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. There is an important concept evident in all three of these equations - the period, speed and the acceleration of an orbiting satellite are not dependent upon the mass of the satellite. The orbital velocity of a satellite increases with the radius of the orbit II. Does the comet have a constant (a) linear speed, (b) angular speed, (c) angular momentum, These important questions of gravitation will play significant role in clearing concepts of Physics class 11 as well as in revision of 12th students. B. the radius of earth. It does not depend on the direction of projection.

Physics. Similarly, a satellite placed in an orbit at around 1730 kilometers will need a speed of 25,400 kilometers per hour. You can visit our post on quick listing and descriptions of these satellite velocity expressions. its velocity is half the escape velocity. I. Escape velocity does not depend upon the mass or shape or size of the body as well as the direction of projection of the body. This action cannot be undone. The radius of the earth only.

Get important questions of Gravitation Class 11 with their answers. Greater is the height of the satellite, smaller is the orbital velocity. Television communication satellites are at a higher altitude of 36 000 km and only need to … The orbital velocity of the satellite depends on its altitude above Earth. You need some basics of orbital mechanics. The orbital velocity of an artificial satellite in a circular orbit above the earth's surface at a distance equal to radius of earth is v. For a satellite orbiting at an altitude half of earth's radius, orbital velocity is C. the orbital radius. ... Value of orbital velocity does not depend on the mass of the satellite. The derivation you quoted uses a lot of short cuts. If a satellite is revolving very close to the surface of earth, then its orbital velocity does not depend upon.
