Which of the below pendulums will move the slowest, if each one of them is displaced by an angle of $$60^\circ$$ from the center?
The time period of a pendulum(T) =2$$ \pi \sqrt{\frac{l}{g} }$$.
The time period is directly proportional to the length of the pendulum.
More the time period, lesser will be the speed of the pendulum.
So Option B is correct.
