A particle moving along the x-axis executes simple harmonic motion, then the force acting on it is given by
A
– A Kx
B
A cos (Kx)
C
A exp (– Kx)
D
A Kx
Where A and K are positive constants
Answer
– A Kx
Explanation
Solution
For S.H.M. F=−kx.
∴ Force = Mass × Acceleration ∝ – x
⇒ F = – Akx; where A and k are positive constants.
