Solution

## The correct options are A Velocity D velocity If two earth-satellites are revolving in the same circular orbit round the center of the earth, then the orbital radius is the same. According to Kepler's Laws of planetary motion, T2∝R3 where T: Time period of the satellite R: Radius of the orbit As R is the same for both the satellites, time period is equal. Orbital velocity of the satellite is given by: v=2πRT As R and T is same for both the satellites, the speeds are equal for the two satellites. Mass of the two satellites need not be the same. Also, energy of the satellite is dependent on the mass and hence, the energies also need not be the same.  Suggest Corrections  0      Similar questions  Explore more
