Question

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

Answer 1

Hey!

We know,

Let mass be m

Ratio = P.E of A/P.E of B
          = mgh/mg2h
          = 1:2

Hope This helps You!

Answer 2

Let the masses of the bodies be M

we know that potential energy=mgh

potential energy of A=mgh

potential energy of B=mg2h

the ratio of their potential energy=mgh/mg2h

=1/2

=1: 2

[Note -this is the ratio of potential energy of A to B If you want ratio of potential energy of B to A then it is 2: 1 you didn't mentioned in question]
