Question

Ajay and Atul have been asked to determine the potential energy of a ball of mass m kept on a table as shown in the figure. What answers will they get? Will they be different? What do you conclude from this?

Answer 1

As seen from the picture, the heights of the ball with respect to Ajay

and Atul are different. Also, given that the potential energy is relative, the potential energy with respect to them will also be different.
