Question

The potential energy of a body of mass 0.5 kg increases by 100 J when it is taken to the top of a tower from the ground. If force of gravity on 1 kg is 10 N, what is the height of the tower ?

​

Answer 1

Answer:

Explanation:

Potential energy = (m g) h 100 J = (0.5 × 10) N × h h = (100/ 0.5) x 10 = 100/(5/10) x 10 = 20
