Questions  

The maximum acceleration of a particle in SHM is made four times keeping the  maximum speed to be constant. It is possible when

a
amplitude of oscillation is doubled while frequency remains constant
b
amplitude of oscillation is doubled while frequency is halved
c
amplitude of oscillation is made one-fourth while frequency is made four times
d
amplitude of oscillation remains constant while frequency is doubled

detailed solution

Correct option is C

amax=Aω2   ......(1)vmax=Aω     ........(2)⇒amax=vmaxωSince,  vmax is constant, to make amax  four times, ω should be made four times.From (1), A should be made one-fourth.
