Question

Does time period of a simple pendulum depend upon radius of bob

Answer 1

yes

Explanation:

as in second's pendulum time period is 2 seconds and length about 1m

if we increase the length time period decrease

Answer 2

$\Huge\bf\purple{\mid{\overline{\underline{Answer}}}\mid}$

Yes it does depend on the radius of the bob

The equation of time period of a pendulum is

$\pink{ \dashrightarrow{T = 2\pi \sqrt{ \dfrac{l}{g} } }}$

Since 2π is a constant , the time period mainly depends on 2 parameters :

$\bigstar$Length of pendulum

$\bigstar$Gravitational acceleration at that place

Concept:

Length of pendulum means the distance of centre of mass of Bob from the separation distance. It doesn't just signify the real length of the string from which the Bob hangs.

Another thing is that :

Gravitational acceleration at any place depends on many factors like latitude , rotational motion of Earth , altitude of that place , etc. All these factor determine the time period of a pendulum.
