VITEEE 2015 Sample Questions › Mechanics questions › SHM

1.. Identify the correct statement:

1) simple pend. with bob of mass M swings with the angular amplitude of 40Â°. When its angular amplitude is 20Â°, tension in string is Mgcos20Â°.

2) the greater the mass of pendulum the shorter is its frequency.

3) fractional change in time peroid of pendulum on changing temp. is independent of lenght of pendulum.

4) as the lenght of simple pend is increased the max. vel of its bob during oscillation will also increase.
