Question

Two simple pendulums A and B have equal lengths, but their bobs weigh 50 gf and 100 gf respectively. What would be the ratio of their time periods? Give reason for your answer.

Answer 1

$T=2\pi \sqrt{\frac{l}{g}}$

Time period does not depend on the weight of the bob.

So, the ratio of time period will be equal to 1.
