Q.
A. The greater the mass of the pendulum bob, the shorter is its frequency of oscillation
B. A simple pendulum with a bob of mass 'm' swing with an angular amplitude of 40º. When its angular amplitude is 20º the tension in the string is less than Mg cos 20º
C. As the length of a simple pendulum is increased, the maximum velocity of its bob during its oscillation will also increase
D. The fractional change in the time period of a pendulum on changing the temperature is in independent of the length of the pendulum
E. None of the above
Correct choice: C
