The maximum acceleration of a particle in SHM is made two times keeping the maximum speed to be constant. It is possible when
amplitude of oscillation is doubled while frequency remains constant
amplitude is doubled while frequency is halved
frequency is doubled while amplitude is halved
frequency of oscillation is doubled while amplitude remains constant
ωA= constant and ω2A is made two times.This is possible when frequency (ω) is doubled and amplitude (A) is halved.
