Question

If a simple pendulum makes 44 complete back-and-forth cycles of vibration in 11 seconds, its period is equal to:

• A. 4 s
• B. 0.25 s
• C. 11 s
• D. 2 s

Answer 1

The correct option is B 0.25 s

Time period is the time taken for one complete vibration.
Time taken for 44 vibrations is 11 s
So, time taken for 1 vibration would be:
$T=\frac{11s}{44}$
$T=0.25s$
Hence, time period is. 0.25 s
