Two masses m and 2m are attached to two ends of an ideal spring as shown in figure. When thye spring is in the compressed state, the energy of the spring is 60 J, if the spring is released, then at its natural length

the energy of both bodies will be same

energy of smaller body will be 10J

energy of smaller body will be 20J

energy of smaller body will be 40 J
