A simple pendulum of length 25 cm has a time period of 1 s and another pendulum of length 100cm has a time period of 2s. The time period of a simple pendulum of length 125 cm will be

The bob of a simple pendulum of length 1 m has mass 100 g and a speed of 1.4 m/s at the lowest point in its path. Find the tension in the stirng at this instant.

The mass of a simple pendulum bob is 100 gm. The length of the pendulum is 1 m. The bob is drawn aside from the equilibrium position so that the string makes an angle of 60^(@) with the vertical and let go. The kinetic energy of the bob while crossing its equilibrium position will be

There is one large vertical non-conducting plane surface with uniformly distributed charge. A pendulum bob is suspended through an insulating string from a point on this non-conducting surface. The length of the string is l and mass of the bob is m. The charge carried by the pendulum bob is q. It is found that in a state of equilibrium, the string of the pendulum makes 60^@ angle with the vertical. What will be the charge per unit area on surface? Also calculate the tension developed in the string in equilibrium state.

A pendulum bob has a speed of 3ms^(-1) at its lowest position. The pendulum is 0.5 m long. The speed of the bob, when string makes an angle of 60^(@) to the vertical is ("take, g"=10ms^(-1))

A pendulum bob has a speed 3m/s while passing thorugh its lowest position. What is its speed when it makes an angle of 60^0 with the vertical? The length of the pendulum is 0.5m Take g=10 m/s^2 .

A pendulum consists of a 2.0 kg stone swinging on a 4.5 m string of negligible mass. The stone has a speed of 8.0 m/s when it passes its lowest point. (a) What is the speed when the string is at 60^(@) to the vertical ? (b) What is the greatest angle with the vertical that the string will reach during the stone's motion ? (c) If the potential energy of the pendulum-Earth system is taken to be zero at the stone's lowest point, what is the total mechanical energy of the system ?

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.

Consider a pair of identical pendulums, which oscillate with equal amplitude independently such that when one pendulum is at its extreme position making an angle os 2^(@) to the right with the vertical , the other pendulum makes an angle of 1^(@) to the left of the vertical. What is the phase difference between the pendulums?

A simple pendulum is constructed by attaching a bob of mas m to a string of length L fixed at its upper end. The bob oscillates in a vertical circle. It is found that the speed of the bob is v when the string makes an angle theta with the vertical. Find the tension in the string at this instant.
