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 ground. If force of gravity on 1 kg is 10 N, what is the height of the tower ?

Solution

P.E. = Force × height
Potential energy = (m g) h
100 J = (0.5 × 10) N × h

h= `100/(0.5 '10)` = `100/(5/10 '10` =20 m

  Is there an error in this question or solution?
