If a simple pendulum is taken to a place where $g$ decreases by $4\%$,then the time period

$A$ simple pendulum of period $T$ has a metal bob which is negatively charged. If it is allowed to oscillate above a positively charged metal plate,its period will

If the length of a seconds pendulum becomes $\frac{1}{3}$ of its original length,what will be its new periodic time?

Identify the correct statement among the following.

$A$ second's pendulum is mounted in a rocket. Its period of oscillation decreases when the rocket

$A$ simple pendulum of length $1 \,m$ is freely suspended from the ceiling of an elevator. The time period of small oscillations as the elevator moves up with an acceleration of $2 \,m/s^2$ is (use $g=10 \,m/s^2$).
