We know that, U=(-GMm/r) As r increases, U also increases.

Q. An earth satellite is moved from one stable circular orbit to a further stable orbit, then among the following which one will increase?

Linear orbital speed

Centripetal acceleration

Gravitational potential energy

Gravitational force

We know that, $U = \frac{- GM m}{r}$ As r increases, U also increases.
