Question

The equation of SHM of a particle is a + 4π²x = 0 where α is instantaneous linear acceleration at displacement x, the frequency of motion is –

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

Answer 1

Answer: (A)

1Hz

Answer 2

Comparing A + ω²x = 0 ⇒  ω² = 4π² ⇒ ω = 2π

2πn = 2π ⇒  n = 1 Hz
