प्रश्न
Two bodies A and B of equal masses are kept at heights of h and 2h respectively. What will be the ratio of their potential energies?

उत्तर
Potential energy of a body is directly proportional to the height of the object.
Hence , `"Potential energy of A"/"Potential energy of B" = 1/2`
Ratio of A and B = 1:2
