Calculate the tension in a string that whirls a 2 kg - toy in a horizontal circle of radius 2.5 m when it moves at 3m/s.

If maximum and minimum tension in the string whirling in a circle of radius 2.5 m are in the ratio 5 : 3 then its velocity is

The maximum and minimum tension in the string whirling in a circle of radius 2.5m are in the ratio 5 : 3 , then the velocity is—

A ball of mass 0.1 kg is suspended by a string 30 cm long. Keeping the string always taut, the ball describes a horizontal circle of radius 15 cm. Find its angular speed and tension.

A lift of mass 400 kg is hung by a wire. Calculate the tension in the wire when the lift is (a) at rest, (b) moving upward with a constant acceleration of 2.0 m//s^(2) and (c) moving downward with an acceleration 2.0 m//s^(2) .

A stone tied to the end of a string 80 cm long is whirled in a horizontal circle with a constant speed. If the stone makes 14 revolutions in 25 s, what is the magnitude and direction of acceleration of the stone?

One end of a string of length L and cross sectional area A is fixed to a support and the other end is fixed to a bob of mas m. The bob is revolved in a horizontal circle of radius r with an angular velocity omega such that the string makes an angle theta with the vertical. Young's modulus is Y. The tension T in the string is
