Q. Which of the following affects the time period of a simple pendulum?

निम्नलिखित में से कौन एक सरल लोलक की समयावधि को प्रभावित करता है?

Shape of bob
बॉब का आकार

Mass of bob
बॉब का द्रव्यमान

Length of string
डोरी की लंबाई

Amplitude (if large)
आयाम (यदि बड़ा हो)

The time period (T) of a simple pendulum is given by:

T = 2\pi \sqrt{\frac{L}{g}}

So, only the length (L) of the string affects the time period (for small amplitudes). Mass, shape, and amplitude (if small) do not affect T.
