Physics - Rotation Question with Solution | TestHub

A simple pendulum of length $2\mathrm{m}$ is given a horizontal push through angular displacement of $60^{\circ }$. If the mass of bob is 200 gram, the angular velocity of the bob will be (Take Acceleration due to gravity $=10\mathrm{m}/{\mathrm{s}}^2$ ) $\left(\sin 30^{\circ }=\cos 60^{\circ }=0.5,\cos 30^{\circ }=\sin 60^{\circ }=\sqrt{3}/2\right)$
