# Two 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 ? - ICSE Class 8 - Physics

ConceptGravitational Potential Energy

#### Question

Two 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 ?

#### Solution

Body A                                               Body B

P.E_1=m_1gh                                P.E_2=m_2gh

P.E_1=10×gh                                  P.E_2=20 ×gh

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.

Is there an error in this question or solution?
