Question

For a particle performing linear S.H.M. Its average speed over one oscillation is (a = amplitude of S.H.M, n = frequency of oscillation)

• A. $2an$
• B. $4an$
• C. $6an$
• D. $8an$

Answer 1

The correct option is B $4an$

In SHM:-

Distance covered per oscillation, $s=4a$

Time taken for one oscillation, $T=\frac{1}{n}$

Hence, average speed per oscillation, $v_{av}=\frac{S}{T}=4an$

Hence, correct answer is option-(B).
