a) Consider Figure 1. Determine the magnitude and direction of the net gravitational force exerted on the 0.1 kg sphere. Why is the force from the smaller sphere is greater than the bigger sphere? [5 marks] b) A particle at rest is attracted toward a center of force according to the relation F = -mk² / x³. Show that the time required for the particle to reach the force center from a distance d is d² lk.
