A string of length L fixed at one end carries a mass M at the other end. The string makes `2/pi` revolutions per second around the vertical axis through the fixed end as shown in the figure what is the tension in the string ?

A body at the end of a string moves in a vertical circle. The string always pulls the body towards the centre of the circle. Find the tension in the string when the body is at the highest point and at the lowest point.

A light string passes over a pulley. To one of it's ends 6 kg is attached. To the other end a mass of 10 kg attached. The tension in the string will be

Breaking tension of string of length 1m is 40N. A body of mass 100g, is tied to the one end of the string and revolved in horizontal circle with another end fixed. Find maximum Angular velocity

A half kg weight is tied to one end of a metal wire of length 0.6 m . By holding the other end in the hand, the wire is whirled in a vertical and has an angular velocity of 2 r.p.s. at bottom of the circle. What is the elongation of the wire at the lowest point ? Area of cross-section of the wire = 5 x 10 ^(-6) m^2 . Y for steel = 2 x 10^10 N/m^2 .

Two weights are suspended from a string thrown over a light frictional pulley. The mass of one weight is 200g. If a heavy mass M is attached to the other end, the tension in the string is ?

Two small balls having equal positive charges Q coulomb on each are suspended by two insulating strings of equal length L metre from a hook fixed to a stand. This whole setup is taken in a satellite into space, where there is no gravity (state of weightlessness). What is the angle between the strings? Find out the tension in each string.
