If the amplitude of linear S.H.M. is decreased then
- A its period and total energy will increase
- B its period will increase, and total energy will decrease
- C its period and total energy will decrease.
- D its period will not change but total energy will decrease
Answer & Solution
Correct Answer
(D) its period will not change but total energy will decrease
Step-by-step Solution
Detailed explanation
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.
\(
\mathrm{E}=\frac{1}{2} \mathrm{~m} \omega^2 \mathrm{~A}^2
\)
Hence its energy will decrease if amplitude is decreased.
