The angular amplitude of a simple pendulum is $\theta_0$. The maximum tension in its string will be
$mg \left(1-\theta_0\right)$
$mg \left(1+\theta_0\right)$
$mg \left(1-\theta_0^2\right)$
$mg \left(1+\theta_0^2\right)$
The periodic time of a simple pendulum of length $1\, m $ and amplitude $2 \,cm $ is $5\, seconds$. If the amplitude is made $4\, cm$, its periodic time in seconds will be
If the length of a clock pendulum increases by $0.2 \%$ due to atmospheric temperature rise, then the loss in time of clock per day is ........... $s$
In a simple pendulum, the period of oscillation $T$ is related to length of the pendulum $l$ as
The period of oscillation of a simple pendulum of constant length at earth surface is $T$. Its period inside a mine is
The time period of oscillations of a simple pendulum is $1$ minute. If its length is increased by $44 \%$. then its new time period of oscillation will be ......... $s$
