Question

The Bob of a simple pendulum of mass100g is oscillating with a time period of 1.42s if the Bob is replaced by another Bob of mass 150 but of same radius. The new time period is

Answer 1

answer=

Time period of simple pendulum T=2π

g

l

⟹ Time period of simple pendulum is independent of mass of the bob but depends on the length of the string.

Thus, time period of oscillation of another bob is also 1.42 seconds.
