Question

If a body of mass 2 kg is at a height of 2 m, then find the gravitational potential energy with respect to earth (g =10 m/s2).

  1. 30
  2. 40
  3. 20
  4. 60

hintHint:

U= mgh

The correct answer is: 40


    • The formula for potential energy due to gravity is U = mgh.
    • In this case, a body of mass 2kg kept at a height of 2m. 
    • Therefore, gravitational potential energy is given as 2×10×2= 40J.
    • So, the correct option is b.
