Solution

The correct option is C
The gravitational potential energy U(r) due to a shell at a distance r, where a point mass m is placed is:
For rR:
U(r)=GMmR
It will be constant in negative value

For r>R:
U(r)=GMmr
It will be increasing from negative to a positive value in hyperbolic manner.

Hence, option 'c' is correct.
