Questions  

A bead X resting on a smooth horizontal surface, is connected to two identical springs and is made to oscillate to and fro along the line of the springs. When the bead passes through the central position. its energy is

a
mostly potential energy
b
all potential energy
c
half potential energy and half kinetic energy
d
all kinetic energy

detailed solution

Correct option is D

When bead passes through central position there will not be any deformation of spring hence no potential energy, all energy will be kinetic

Two similar springs P and Q have spring constants Kp and KQ such that Kp > KQ. They are stretched first by the same amount (case a), then by the same force (case b). The work done by the springs WP and WQ are related as, in case (a) and case (b), respectively.
