Question

A particle is undergoing a SHM of amplitude 10cm. What should be the minimum value of acceleration at an extreme position for maximum speed at centre to be 5m/s?

(a) 20m/s^2

(b) 5m/s^2

(c) 0

(d) 250m/s^2

The question was posed to me during an interview.

Origin of the question is Oscillations in division Oscillations of Physics – Class 11

Answer 1

The correct option is (d) 250m/s^2

Explanation: vmax = Aw.

5 = 0.1w.

w = 50s^-1.

amin at extreme = Aw^2

= 0.1*50*50

= 250m/s^2.
