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)

Options

• 2 an

• 4 an

• 6 an

• 8 an

Answer 1

For a particle performing linear S.H.M., its average speed over one oscillation is 4 an. (a = amplitude of S.H.M., n = frequency of oscillation)

Explanation:

Distance travelled in one oscillation = 4a

Average velocity = `"total distance"/"Time"`

= `(4"a")/"T"`

= 4 an [∴ n = `1/"T"`]
