1.	Four particles each of mass M are placed at the four corners of a square of side L. Calculate the gravitational potential energy of the system.
Answer» Since the force required to LIFT it is equal to its WEIGHT, it follows that the gravitational potential energy is equal to its weight times the HEIGHT to which it is lifted. PE = KG x 9.8 m/s2 x m = joules.
