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)
