Question

A pendulum is hung from the roof of a sufficiently high building and is moving freely to and fro like a simple harmonic oscillator. The acceleration of the bob of the pendulum is 20 m s - 2 at a distance of 5 m from mean position. The time period of oscillation is, 2 s, π s, 2 π s, 1 s

MARKS App · Accepted Answer

Acceleration in SHM is a = ω 2 x 20 = ω 2 5 ⇒ ω 2 = 4 ⇒ ω = 2 ⇒ 2 π T = 2 T = π s
