The total mechanical energy of a particle of mass m executing SHM with the help of a spring is E = (1/2)m ω 2 A 2 . If the particle is replaced by another particle of mass m/2 while the amplitude A remains same. New mechanical energy will be:
A
E
B
2E
D
E/2 E
Text Solution
Verified by ExpertsThe correct answer is:
D
E = 
m ω 2 A 2
= 
m × 
× A 2
= 
kA 2
E is independent of mass.
