Question

A simple pendulum is executing SHM with a period of 6 s between two extreme positions B and C about a point O. If the length of the arc BC is 10 cm, how long will the pendulum take the move from position C to a position D towards O exactly midway between C and O?

• A. 0.5 s
• B. 1 s
• C. 1-5 s
• D. 3 s

Answer 1

Answer: (C)

1-5 s

Answer 2

Particle is executing SHM. Since, T = 6 s Obviously, time taken from O to C will be 3 s. So, time taken from C to $D=\frac{T}{4}=\frac{6}{4}=1.5\,s$
