Potential energy of a body at a height h is 100 J. If height is doubled, the potential energy becomes

Question

Team JKSSB Mock Tests · Accepted Answer

PE = mgh, so directly proportional to height h. If h becomes 2h, PE becomes 2 × 100 = 200 J, assuming g constant. For large heights, g varies, but basic assumption. Thus 200 J.
