- A
The greater the mass of a simple pendulum bob, the shorter is its frequency of oscillation
- B
A simple pendulum with a bob 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 $Mg$ $\cos 20^o$
- C
As the length of a simple pendulum is increases, the maximum velocity of the bob for the same amplitude, during its oscillation also increases
- D
The fractional change in the time period of a pendulum on changing the temperature is independent of the length of the pendulum
