Question

A simple pendulum takes $5$ seconds to complete $12$ oscillations. What will be the time period of pendulum?

• A. $0.42s$
• B. $0.5s$
• C. $0.12s$
• D. $0.60s$

Answer 1

The correct option is A $0.42s$

Time period is the time taken to complete one oscillation.

12 oscillations take 5 seconds.
$\therefore$1 oscillation takes $\frac{5}{12}s=0.42s$.
