Questions
A particle performs S.H.M. of amplitude A along a straight line. When it is at a distance A from mean position, its kinetic energy gets increased by an amount due to an impulsive force. Then its new 2 amplitude becomes
detailed solution
Correct option is C
Due to impulse, the total energy of the particle becomes:12mω2A2+12mω2A2 = mω2A2Let ‘A’ be the new amplitude.∴ mω2(A')2 = mω2A2⇒A' = A.Talk to our academic expert!
