Question

Two balls of masses 'm each are raised to height 'h' and '2h' respectively .What will be rthe ratio of their potential energies?​

Answer 1

U'/ U" = mgh' / mgh"

U'/U" = h/2h

U'/U" = 1/2

U':U" = 1:2 .....

where U' & h' represents ball 1s ht and KE

and U" & h" represents ball2s ht and KE
