JEE MAIN - Physics (2021 - 22th July Evening Shift - No. 16)
T0 is the time period of a simple pendulum at a place. if the length of the pendulum is reduced to $${1 \over {16}}$$ times of its initial value, the modified time period is :
4 T0
$${1 \over {4}}$$ T0
T0
8$$\pi$$ T0
Explanation
$$T = 2\pi \sqrt {{l \over g}} $$
$$T' = {{{T_0}} \over 4}$$
$$T' = {{{T_0}} \over 4}$$
