Question

The equation of SHM of a particle is a + 4p²x = 0 where a is instantaneous linear acceleration at displacement x, the frequency of motion is –

• A. 1 Hz
• B. 4pHz
• C. $\frac{1}{4}$Hz
• D. 4 Hz

Answer 1

Answer: (A)

1 Hz

Answer 2

Comparing

a + w²x = 0

w² = 4p² Ž w = 2p

2pn = 2p Ž n = 1 Hz
