Question

A particle of mass 10 grams is executing S.H.M. with an amplitude of 0.5 meter and circular frequency of 10 radian/sec. The maximum value of the force acting on the particle during the course of oscillation is

• A. 25 N
• B. 5 N
• C. 2.5 N
• D. 0.5 N

Answer 1

Answer: (D)

0.5 N

Answer 2

Maximum force = mass × maximum acceleration =$\mathbf{m}\mathbf{\omega}^{\mathbf{2}}\mathbf{a}\mathbf{= 10}\mathbf{\times}\mathbf{1}\mathbf{0}^{\mathbf{-}\mathbf{3}}\mathbf{(10}\mathbf{)}^{\mathbf{2}}\mathbf{(0.5)}$ = 0.5 N
