Development of the dynamic gravitational field experiment provides us with the precise test for the inverse-square law of gravitation because this method is free from effects of the background mass distribution. However, since the previous experiments were performed by direct measurement of the force between masses, requirements for the detecting system were severer than those of null measurement. We show here the feasibility of the null experiment with advantages attendant on the dynamic method.
