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

Correct Answer: C

Solution :

  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\[D=\frac{T}{4}=\frac{6}{4}=1.5\,s\]
