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 ?​

Answer 1

Explanation:

g =10 m/s^2, m = 0.5 kg, ∆PE = 100 J

∆PE =m*g*h = 0.5*10*h

h = 100/5 = 20 m
