A partical of mass `m` is attached to a massless string of length `l` and is oscillating in a vrtical plane with the other end of the string fixed to a rigid support. The tension in the string at a certain instant is `T=kmg` .

A particle of mass m is tied to a string of length L and whirled into a horizontal plan. If tension in the string is T then the speed of the particle will be :

A ball of mass m is attached to a string whose other end is fixed. The system is free to rotate in vertical plane. When the ball swings, no work is done on the ball by the tension in the string. Which of the following statement is the correct explanation?

A particle of mass 1 kg is attached to a string of length 5 m . The string is attached to a fixed point O . It is released from theposition as shown in Fig. Calculate a. the impulse developed in the string when it becorries taut, b. the velocity of the particle just after the string becomes taut, c. the impulse developed in this string PQ at this instant.
