(a)
For all such problems the gravitational potential energy means the difference in potential energy of the particle from that at a particular reference level. Mostly the reference level is taken as the surface of earth and the gravitational potential energy of a particle of mass m, at a height h above the surface of earth, is given by m*g*h.
Here we may take the top level ...

Solution Summary

A particle is attached to three different springs such that two springs are in parallel and one in series with this parallel combination. The particle is in displaced position from its equilibrium position. The different parts of the question are solved for required energies.
