Objects with masses of 200. kg and 500. kg are separated by
0.400 m. (a) Find the net gravitational force exerted by these
objects on a 50.0-kg object placed midway between them. (b) At
what position (other than infinitely remote ones) can the
50.0-kg object be placed so as to experience a net force of zero?
