1.	Particles of masses m_(1) and m_(2) are at a fixed distance apart. If the gravitational field strength at m_(1) and m_(2) are vec(I_(1)) and vec(I_(2)) respectively.
Answer» `m_(1)VEC(I)_(1) + m_(2)vec(I)_(2) = 0` `m_(1)vec(I)_(2) + m_(2)vec(I)_(1) = 0` `m_(1)vec(I)_(1) - m_(2)vec(I)_(2) = 0` `m_(1)vec(I)_(2) - m_(2)vec(I)_(1) = 0` ANSWER :A
