A satellite is moving in a circular orbit of radius $$2R$$ around earth (Radius$$ $$=$$ $$R) and its total energy is found to be E. If radius of earth shrinks to half of its present radius keeping its mass unchanged, Then potential energy of the satellite when it is on the surface of earth will be

Question

Infinity Learn · Accepted Answer

$$E=-GMm2(2R)=-GMm4RWhen$$ the satellite is placed on the surface of earth (Radius$$ $$R/2), $$U=-GMmR/2=2$$ x $$4E=8E$$
