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 small ball is hung by a string fixed to a wall. The ball is pushed away from the wall. The forces action on the ball are shown in the diagram. Which of the following statements is wrong?

A ball of mass 1.00 kg is attached to a loose string fixed to a ceiling. The ball is released from rest and falls 2.00 m, where the string suddenly stops it. Find the impulse on it from the string.

A particle of mass m is attached to one end of a light inextensible string and the other end of the string is fixed in vertical plane as shown. Particle is given a horizontal velocity u = sqrt((5)/(2)gl) The tension in the string at an instant when acceleration of the particle is horizontal and sqrt(3)g is

A small ball of mass m hits the cylinder which is hinged at top and free to rotate in vertical plane as shown in figure. Mass of cylinder is M. Linear momentum of system (ball+cylinder)

A small ball of mass m is attached to the end of the string of length l=1 m whose other end is fixed. From its lowest position, the ball is given a kinetic energy ml/5. the net acceleration (in m//s^(2) ) of the ball at the instant when the string makes an angle theta of 37^(@)C with the downwards vertical is___________

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 .
