Explanation / Answer

Part (A) F on 14 kg = G m1 m2 / r^2 = (6.674×1011 x 8 x 14) / (.50)^2 = 2.9 x 10^-10

   acceleration = F/m = 2.9 x 10^-10 / 14 = 2.07 x 10^-11 m/s^2

Part (B) Direction is towards the 8 kg mass because the gravitational force acted on them is an attractive force. So both masses come closer.
