1.	A simple harmonic oscillator has a period of 0.01 s and an amplitude of 0.2 m. The magnitude of the velocity in m/s at the centre of oscillation is……………….
Answer» `20pi` `40pi` `60pi` `80pi` SOLUTION :VELOCITY is maximum at the CENTRE of oscillation and is given by `v_(0)=(2pi)/(T)A=(2pixx0.2)/(0.01)=40pim//s`
