Question

A body of mass 3 kg lies on the surface of the table 2 m high. It is moved on the surface by 4 m the change in P.E will be

Answer 1

Answer:

No change on Potential Energy, i.e. ΔP.E. = 0

Explanation:

P.E. = mgh

thus potential energy directly depends on h.

Since in the above question there is no change in height, the change in P>E> will be zero.
