Question

In a gravitational field, at a point where the gravitational potential is zero 

(A) The gravitational field is necessarily zero 

(B) The gravitational field is not necessarily zero 

(C) Nothing can be said definitely, about the gravitational field 

(D) None of these

Answer 1

Correct option: (A) The gravitational field is necessarily zero

Explanation:

point where gravitational potential is zero, gravitational field has to be zero.

as I = – (dv / dx) i.e. potential is zero then field intensity = 0
