The total mechanical energy of a spring-mass system in simple harmonic motion is E =1/2 m ω^2 A^2 Suppose
The total mechanical energy of a spring-mass system in simple harmonic motion is E =1/2 m ω 2 A2 Suppose the oscillating particle is replaced by another particle of double the mass while the amplitude A remains the same. The new mechanical energy will
(a) become 2E
(b) become E/2
(c) become √2E
(d) remain E.

(d) remain E.
EXPLANATION:
Since no external work is done on the system the energy of the system will remain the same. Hence option (d).
