In a linear Simple Harmonic Motion (SHM) (A) Restoring force is directly proportional to the displacement. (B) The acceleration and displacement are opposite in direction. (C) The velocity is maximum at mean position. (D) The acceleration is minimum at extreme points. Choose the correct answer from the options given below:
Options
- AC and D only
- BA , C and D only
- CA , B and C only
- DA , B and D only
Correct answer
C. A , B and C only
Step-by-step solution
The equations of SHM is given by F = – k x ⇒ a = – ω 2 x Velocity is given by, v = ω A 2 - x 2 . Clearly, velocity is maximum at mean position and acceleration is maximum at extreme positions. Hence, this is the correct option.
