In a certan region of space the gravitaional field is given by -k/r where r is the distance and k is a constant. if the gravitational potential at r= a be v then what is the expression for gravitational potential ?

#U(r) = k ln(r/a) + V#
Explanation:
If the gravitational field is inverse (as opposed to inverse-square), then:
#bbg = - k/r \ bb hat r #
The increase in potential
Because
#U(r) = k ln(r/a) + V#
