Question

Identify the exact statement among the
following:
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 amplitude 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 its bob
during its oscillation will also increase
D. The fractional change in the time period of a
pendulum on changing the temperature is
independent of the length of the pendulum.​
