Two satellites A and B move round the earth in the same orbit. The...

The formula to calculate the speed of a satellite while revolving around the Earth is given by

$v = \sqrt{\dfrac{G{M}_{e}}{R}} . . . \left(1\right)$

where, $v$ is the speed, $G$ is the Gravitational constant, ${M}_{e}$ is the mass of the Earth, $R$ is the radius of the orbit.

As can be seen from the equation, speed is independent of mass of satellite.

Hence, the speed of the satellites will be the same.
