# 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 ?

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 = r0 be V0 , then what is the expression for the gravitational potency V ?

(a) k log (r/r0)

(b) k log (r0/r)

(c) V0 + k log (r/r0)

(d) V0 + k log (r0/r)
