A simple pendulum of length / is vibrating with an amplitude A.Its energy is E. Consider the following situations:
(i) Amplitude is doubled keeping length the same
(ii) Length is doubled, keeping amplitude the same.
Then energy of the pendulum in the two situations will be:
detailed solution
Correct option is A
E=12mω2A2(i) A'=2A⇒E'=4E(ii) T∝l⇒T'=2T,E'∝ω2∝1T2⇒E'=E2Talk to our academic expert!
