Answer:
3s is longer
2s is shorter
Explanation:
A pendulum is made up of a ball which is referred to as a mass attached to a string which is usually massless.
A period is one swing of the pendulum over and back.
Two pendulums with the same length but different masses would have the same period
When two pendulums with different lengths, the pendulum with the longer length would have a longer frequency and thus the longer period while the pendulum with the shorter length wold have the shorter period
