Identify the correct statement from the following.

Options

A. The greater the mass of a pendulum bob, the shorter is its frequency of oscillation
B. A simple pendulum with a bob of mass M swings with an angular amplitude of `40^(@)`. When its angular displacement is `20^(@)`, the tension in the string is less than Mg cos `20^(@)`
C. As the length of a simple pendulum is increased, the maximum velocity of the bob during its oscillation will also increase
D. The fractional change in the time period of a pendulum on changing the temperature depends upon the length of the pendulum

Answer

C
