Two spheres A and B are placed in the arrangement shown below.

(a) If mA = 2m and mB = 7m, where on the dashed line should a third sphere C of mass 7m be placed so that the net force on it is zero? (Select 1)
-between A and B, closer to B
-at the midpoint between A and B
-to the left of B
-to the right of A
-between A and B, closer to A

(b) If the distance between the two spheres A and B is 500 cm, find the location for the third sphere C so that the net force on it is zero.
