One end of a V-tube containing mercury is connected to a suction pump and the other end to atmosphere. The two arms of the tube are inclined to horizontal at an angle of 45° each. A small pressure difference is created between two columns when the suction pump is removed. Will the column of mercury in V-tube execute simple harmonic motion? Neglect capillary and viscous forces.Find the time period of

A simple pendulum of time period 1s and length l is hung from a fixed support at O, such that the bob is at a distance H vertically above A on the ground (Fig. ). The amplitude is o θ . The string snaps at` θ = θ_ 0 /2`. Find the time taken by the bob to hit the ground. Also find distance from A where bob hits the ground. Assume θ 0 to be small so that ` sinθ_0 and cos θ_0 =1`
