A bob of mass 1 kg is suspended from an inextensible string of length 1 m. When the string makes an angle `60^(@)` with vertical, speed of the bob is 4 m/s
Net acceleration of the bob at this instant is

A bob of mass 1 kg is suspended from an inextensible string of length 1 m. When the string makes an angle 60^(@) with vertical, speed of the bob is 4 m/s Upto what maximum height will the bob rise with respect to the bottommost point ?

A mass of 0.1kg is rotated in a verticla circle using a string of length 1m. When the string makes an angle 30^(@) with the vertical, the speed of the mass is 2 ms^(-1) . The radial acceleration of the mass at that instant is

A bob hangs from a rigid support by an inextensible string of length l. It is released from rest when string makes an agngle 60^(@) with vertical . The speed of the bob at the lowest position is

A body of weight 10 N attached to one end of a string of length 1m is rotated in a vertical plane. At the instant when the string makes an angle of 60^(@) with the downward vertical the speed of the bob is sqrt(9.8) ms^(-1) . The tension in the string at that instant is equal to
