A) the speed of P is equal to that of Q
B) the speed of P is greater than that of Q
C) the speed of P is less than that of Q
D) the kinetic energy of P is equal to that of Q
E) the potential energy of P is equal to that of Q, taking the potential energy of a body to be zero at infinity
Correct Answer: A
Solution :
Orbital speed of a satellite is given by \[{{v}_{o}}=\sqrt{\frac{GM}{r}}\] Hence, it does not depend upon the mass of satellite, hence speed of P is equal to that of Q.
