	The period of simple pendulum is measured as T in a stationary lift. If the lift moves upwards with an acceleration of 5 g, the period will be
	The length of a simple pendulum is increased by 1%. Its time period will
	A simple pendulum with a bob of mass $m$ oscillates from A to C and back to A such that PB is $H$. If the acceleration due to gravity is $g$, then the velocity of the bob as it passes through B is
	Identify correct statement among the following
	The bob of a pendulum of length $l$ is pulled aside from its equilibrium position through an angle $\theta $ and then released. The bob will then pass through its equilibrium position with a speed $v$, where v equals
	A simple pendulum executing S.H.M. is falling freely along with the support. Then
	A pendulum bob has a speed of $3 m/s$ at its lowest position. The pendulum is $0.5 m$ long. The speed of the bob, when the length makes an angle of ${{60}^{o}}$ to the vertical, will be (If $g=10m/{{s}^{2}}$)
	The time period of a simple pendulum is 2 sec. If its length is increased 4 times, then its period becomes
	If the metal bob of a simple pendulum is replaced by a wooden bob, then its time period will
	In a simple pendulum, the period of oscillation $T$ is related to length of the pendulum $l$ as
