Explanation:

A rectangular object of mass 6 kg is taken to a height of 20 m from the ground.

Calculate the potential energy gained by this object. Take g = 10 m/s?.

Show three different paths through which the object can be taken to this height. Also

calculate the potential energy for all these three paths and write your conclusion.
