if three springs of spring constant k,2k,3k are in series in vertical position with a block of mass m attached to the lowest spring (i.e. 3k )then find the potential energy of each spring if the block idd=s in the mean position.

For springs, when they are in series,
1/Keff = 1/k + 1/2k + 1/3k
Hence find total energy = ½ x Keff x s2
Then distribute the energy by their extension as extension is inverse of k.
