In a certain region of space, the gravitational field is given by

-k/r

, where

r

is the distance and

k

is a constant. If the gravitational potential at

r = {r_0}

be

{V_0}

, then what is the expression for the gravitational potential V?

View answer and explanation

Correct option: C

{V_0} + k\log \left( {r/{r_0}} \right)

Option C (

{V_0} + k\log \left( {r/{r_0}} \right)

) is correct because it is derived from integrating the gravitational field to find the gravitational potential.
