A point mass m is connected with ideal inextensible string of length l and other end of string is tied at point O as shown in the figure. The string is made horizontal and mass is released from point A to perform vertical circular motion. There is a nail at point N such that ON =r . Find the value of r so that mass m is able to just perform complete vertical circular motion about point N.

A bob is attached to a string of length l whose other end is fixed and is given horizontal velocity at the lowest point of the circle so that the bob moves in a vertical plane. Match the velocity given at the lowest point of circle in column I with tension and velocity at the highest point of the circle corresponding to velocity of column I of column II

A bob of mass m is attached at one end of a string of length l other end of the string is fixed at point O . Bob is rotating in a circular path of radius l in horizontal plane about O with constant speed v , as shown in the figure. The average force exterted by string on the bob during its :- (A) half revolution will be (mv^(2))/(pil) (B) half revolution will be (2mv^(2))/(pil) (C) one fourth revolution will be (sqrt2mv^(2))/(pil) (D) one revolution will be zero Select correct alternative :-

A pendulum consists of a wooden bob of mass M and length l . A bullet of mass m is fired towards the pendulum with a speed v . The bullet emerges immediately out of the bob from the other side with a speed of v//2 and the bob starts rising. Assume no loss of mass of bob takes place due to penetration. If the bob is just able to complete the circular motion, then tension at the lowest point just when the bob starts rising will be
