Q. A satellite is revolving round the earth. If the universal gravitational constant $(G)$ was decreasing uniformly with time for the satellite, the quantity that still remains constant is :

System of Particles and Rotational Motion

Solution:

Due to change in $G$, the graviatinal force and energy changes but as the gravitational force is a central force, net torque on satellite about center of planet still remain zero hence angular momentum of the satellite will remain constant.
