Identify the correct statement
The greater the mass of a simple pendulum bob, the shorter is its frequency of oscillation
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 $Mg$ $\cos 20^o$
As the length of a simple pendulum is increases, the maximum velocity of the bob for the same amplitude, during its oscillation also increases
The fractional change in the time period of a pendulum on changing the temperature is independent of the length of the pendulum
If the length of a pendulum is made $9$ times and mass of the bob is made $4$ times then the value of time period becomes
The period of oscillation of a simple pendulum of constant length at earth surface is $T$. Its period inside a mine is
The motion of a simple pendulum excuting $S.H.M$. is represented by following equation.
$Y = A \sin (\pi t +\phi)$, where time is measured in $second$.
The length of pendulum is .............$cm$
Is the oscillation of a simple pendulum at the centre of the earth be possible ?
''Motion of simple pendulum from mean position for small displacement is a simple harmonic motion'' - Explain this statement.
