Q: In a certain region of space, the gravitational field is given by -K/x , 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 potency V ?

(a) k log (r/r_{0})

(b) k log (r_{0}/r)

(c) V_{0} + k log (r/r_{0})

(d) V_{0} + k log (r_{0}/r)
