If the inertial mass `m_(1)` of the bob of a simple pendulum of length 'l' is not equal to the gravitationalmass`m_(g)`, then its period is

If the inertial mass and gravitational mass of the simple pendulum of length l are not equal, then the time period of the simple pendulum is :

If the metal bob of a simple pendulum is replaced by a wooden bob, then its time period will

If the metal bob of a simple pendulum is replaced by a wooden bob, then its time period will

If a metal bob of a simple pendulum is replaced by wooden bob, then its time period will

The period of a simple pendulum is double, when its length is increased by 1.2 m. The original length of the simple pendulum is
