If the amplitude of linear S.H.M. is decreased then
If the amplitude of linear S.H.M. is decreased then
its period and total energy will increase
its period will increase, and total energy will decrease
its period and total energy will decrease.
its period will not change but total energy will decrease
Solution
The period of the S.H.M. does not depend on the amplitude. Its energy is given by
$\mathrm{E}=\frac{1}{2} \mathrm{~m} \omega^2 \mathrm{~A}^2$
Hence its energy will decrease if amplitude is decreased.
