MCQ
Identify correct statement among the following
- AThe greater the mass of a pendulum bob, the shorter is its frequency of oscillation
- BA simple pendulum with a bob of mass M swings with an angular amplitude of ${40^o}$. When its angular amplitude is ${20^o}$, the tension in the string is less than $Mg\cos {20^o}$.
- ✓As the length of a simple pendulum is increased, the maximum velocity of its bob during its oscillation will also decreases
- DThe fractional change in the time period of a pendulum on changing the temperature is independent of the length of the pendulum
