Question

The time period of a simple pendulum depends on

• A. Mass of bob
• B. Length of string
• C. Dimension of bob
• D. Material of the bob

Answer 1

The correct option is B

Length of string

The time period of a simple pendulum:

1. A body hanging from a fixed point that might also swing back and forth under the effect of gravity is called a pendulum.
2. Pendulums are employed to control clock movement also because the interval of time for each completed oscillation of the pendulum is known as its period and is constant.
3. The pendulum's time period refers to the amount of time it takes the swinging bob to accomplish one oscillation.

Mathematically, the time period of a simple pendulum can be represented as:
$\mathrm{T}=2\mathrm{\pi }\sqrt{\frac{\mathrm{l}}{\mathrm{g}}}$

Here,

l is the length of the pendulum.

g is the acceleration due to gravity.

Therefore, option B is the correct answer.
