JEE MAIN - Physics (2022 - 29th June Evening Shift - No. 10)

The motion of a simple pendulum executing S.H.M. is represented by the following equation.

$$y = A\sin (\pi t + \phi )$$, where time is measured in second. The length of pendulum is

97.23 cm

25.3 cm

99.4 cm

406.1 cm

$$\omega = \pi = \sqrt {{g \over l}} $$

So, $$l = {g \over {{\pi ^2}}}$$

$$ \simeq 99.4$$ cm (Nearest value)
