Q.2.
Consider two satellites A and B. Both move around the earth in the same orbit but the mass of B is twice that of the mass of A.
Q.3.
Two satellites of masseskg andkg revolve around the earth in circular orbits of radiiand 16R. What is the ratio of speeds of the two satellites?
Q.4.
A satellite is seen after every 8 hours. If it rotates opposite to that of the earth, what is its angular velocity about the centre of the earth? Assume the earth is perfectly spherical and the satellite is in the equatorial plane.
Q.5.
If a satellite is orbiting as close to the earth’s surface as possible _____
Q.6.
The radius of a planet is “R” and mass is “M”. A satellite revolves around it in an orbital radius of “r” and an orbital velocity “v”. How would you express the acceleration due to gravity on the surface of the planet?
Q.7.
A satellite revolves around a planet of radius “Q”. If the angular velocity of the satellite is “w” and the radius of the orbit is “4nQ”, where “n” is an integer, what is the acceleration due to gravity on the surface of the planet?
Q.8.
The orbital velocity of a satellite orbiting the earth is half the escape velocity of the earth. What is the height above the surface of the earth at which it is orbiting? (Let the radius of the earth (R) =km).
