1.	Two bodies of masses, M_(1) and M_(2) are placed at a distance .r.. The gravitational potential at the point where the gravitational field is zero
Answer» `-(G)/(r)(M_(1)+2sqrt(M_(1)M_(2))+M_(2))` `-2(G)/(r)(M_(1)+M_(2))` `-(G)/ (r ) (M_(1) + M_(2))^(2)` `-(G)/(r )(SQRT(M_(1)) + sqrt(M_(2)))` ANSWER :A
