Question

The total mechanical energy of a particle of mass m executing shm with the help of a spring is

Answer 1

Answer:

In SHM ω=

m

k

E=

Hence we can clearly see that energy E is independent of mass

So if maas m is replaced by a mass

2

m

Explanation:

Answer 2

E

In SHM    ω=mk

E=21mω2A2

Substituting the value of ω

E=21mmkA2

E=21kA2

Hence we can clearly see that energy E is independent of mass

So if maas m is replaced by a mass 2m

Energy will remain same E
