Answer:
Option (C)
Explanation:
The time period of simple pendulum is defined as the time taken by the bob to complete one oscillation.
The formula to calculate the time period of a simple pendulum is given by
[tex]T = 2\pi \sqrt{\frac{l}{g}}[/tex]
Time period depends on the acceleration due to gravity and the effective length of the pendulum.
The effective length is the sum of length of cord and the radius f bob.
The effective length of the pendulum is defined as the distance between the point of suspension and the centre of gravity of the bob.
