Question

A particle is performing a SHM. If its mass is doubled keeping the amplitude and force constant the same, total energy will become how many times the initial value?

(a) 2

(b) 1/2

(c) 4

(d) 1

The question was posed to me in quiz.

My query is from Oscillations topic in portion Oscillations of Physics – Class 11

Answer 1

Right option is (a) 2

To explain: Total energy = 1/2mw^2A^2.

So, if mass is doubled keeping the amplitude same,

total energy will get doubled.
