Q. If Gravitational constant is decreasing with time, what will remain unchanged in case of a satellite orbiting around earth
A) Time period
B) Orbiting radius
C) Tangential velocity
D) Angular velocity
Explanation
(c) $T^{2} = \frac{4\pi^{2}}{GM}r^{3}$. If $G$ is variable then time period, angular velocity and orbital radius also changes accordingly
