Question

If a simple pendulum
completed 30 oscillations vin
60seconds , what is the time
period of the simple
pendulum?
1. 2s
2.1800S
3.3s
4.9s​

Answer 1

A mass m suspended by a wire of length L is a simple pendulum and undergoes simple harmonic motion for amplitudes less than about 15º. The period of a simple pendulum is T=2π√Lg T = 2 π L g , where L is the length of the string and g is the acceleration due to gravity.
