Q1PhysicsUnit 6: Gravitation
When a satellite falls to an orbit of smaller radius its kinetic energy:
Q2PhysicsUnit 6: Gravitation
Assertion For a very near to the earth's surface the time period of revolution is given by 1h1 h 24min24 m i n Reason The period of revolution of a satellite depends only upon its height above the earth's surface
Q3PhysicsUnit 6: Gravitation
Two satellites are revolving around the earth in circular orbits of same radii. Mass of one satellite is 100 times that of the other. Then their periods of revolution are in the ratio:
Q4PhysicsUnit 6: Gravitation
Two satellites of the same mass are launched in the same orbit around the earth so as to rotate opposite to each other. If they collide inelastically and stick together as wreckage, the total energy of the system just after collision is
Q5PhysicsUnit 6: Gravitation
The ratio of the radii of two planets r1r_{1} and r2r_{2} is k.k . The ratio of acceleration due to gravity on them is r.r . Then the ratio of the escape velocities from them, will be:
