Question

A box is taken to same top by different stairs as shown, which relation holds good for potential energy of box in both cases?

• A. Case 1 > Case 2
• B. Case 1 < Case 2
• C. Case 1 = Case 2
• D. Information insufficient

Answer 1

The correct option is C Case 1 = Case 2

Potential energy depends on the mass of the object and its height from the ground. It does not depends on the path taken to reach that height.
In the given cases mass and the height at which box is placed is same in both cases.Therefore, potential energy of box will be same in both cases.
