04: Energy Class 8 Physics
- #18Two bodies A and B of masses 10 kg and 20 kg respectively are at the same height above the ground. Which of the two has greater potential energy?Ans : :
As g is constant and h is same in both the cases
PE2 is greater than PE.
Hence, Potential energy of body B (more mass) is greater than the P.E. of body A.
Or
As height of body A and is same and ‘g’ is constant, the body with greater mass i.e. body B has greater potential energy.
