Question

The total mechanical energy of a particle of mass m executing SHM is E = 1/2mω2A2. If the particle is replaced by another particle of mass m/2 while the amplitude A remains same. New mechanical energy will be :       

Options

A.√2 E
B.2E
C.E/2
D.E

Solution

E = m ω2A2
= m × × A2
= kA2
E is independent of mass
