Mass of the bob of a simple pendulum of length `L` is `m`. If the bob is projected horizontally from its mean position with velocity `sqrt(4 gL)`, then the tension in the string becomes zero after a vertical displacement of

The bob of a simple pendulum of length L, is displaced through 90^(@) , from its mean position and then released. What will be the tension in the string when the bob of mass m will be its lowest position ?

The bob of a simple pendulum of length L, is displaced through 90^(@) , from its mean position and then released. What will be the tension in the string when the bob of mass m will be at its lowest position?

A simple pendulam of length .l. carries a bob of mass .m.. The bob is released from horizontal position. The tension in the string at t he lowest point would be

The bob of a simple pendulum of length 1m hangs at rest. It is suddenly projected horizontally with velocity 10 ms^(-1) . Calculate the velocity of the bob and tension of the string when it is horizontal. The mass of the bob is (1)/(2) kg. [Hint : See worked out example 4]

The bob of a simple pendulum of length l is given a sharp hit to impart it a horizontal speed of sqrt(3gl) . When it was at its lowermost position. Find angle alpha shown of the string from upside of vertical and speed of the particle when the string becomes slack.
