Question

A and C are the two extreme positions of a pendulum and B is its mean position. The pendulum starts moving from B towards C as shown below. After three and a half oscillations it will be:

• A. at C
• B. at B
• C. at A
• D. somewhere between A and B

Answer 1

The correct option is B at B


The pendulum reaches B after every half an oscillation. Hence, after three and a half oscillations, the pendulum will be at point B.
