Question

If you know that the period of a pendulum is 1.87 seconds, what is the length of that pendulum? (assume that we are on earth and that gravity is 9.81 meters/second². ) a. 0.87 centimeters b. 2.1 meters c. 1.6 meters d. 0.87 meters e. 8.3 meters

Answer 1

The length of the pendulum is 0.087 m. Option d is correct.

What is Simple harmonic motion?

Simple harmonic motion is periodic motion caused by a restoring force that is proportionate to the deviation from equilibrium.

Simple harmonic motion is periodic motion but many other conditions are dependent.

The time period of the pendulum is found as;

$\rm T= 2 \pi \sqrt{\frac{L}{g} } \\\\ \rm 1.87 \ sec= 2 \times 3.14 \sqrt{\frac{L}{9.81 m/s^2} } \\\\ L=0.087 \ m$

The length of the pendulum is 0.087 m

Hence, option d is correct.
