A mass of 0.1 kg is rotated in a vertical circle using a string of legth 20 cm. When the string makes an angle `30^(@)` with the vertical, the speed of the mass is `1.5ms^(-1)`. The tangential acceleration of the mass at that 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 Net acceleration of the bob at this instant is

A particle of mass 200 g , is whirled into a vertical circle of radius 80 cm uisig a massless string The speed of the particle when the string makes an angle of 60^(@) with the vertical line is 1.5ms^(-1). The tension in the string at this position 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 10 kg is suspended from a spring balance. It is pulled aside by a horizontal string so that it makes an angle of 60^(@) with the vertical. The new rading of the balance is

A particle of mass 100 g, is made to describe a vertical circle of radius 1 m. Its instantaneous speed is 1ms^(-1) when the string makes an sngle of 30^(@) with the vertical Find the tension in the string at this position. Can the particle complete its circular path? (g=10ms^(-2))

A small stone of mass 50 g is rotated in a vertical circle of radius 40 cm. What is the minimum tension in the string at the lowest point?

A simple pendulum is constructed by attaching a bob of mass m to a string of length L fixed at its upper end. The bob oscillates in a vertical circle. It is found that the speed of the bob is v when the string makes an angle theta with the vertical. Find the tension in the string at this instant.

A ball of mass 1kg is suspended by an inextensible string 1m long attached to a point O of a smooth horizontal bar resting on fixed smooth supports A and B. The ball is released from rest from the position when the string makes an angle 30^@ with the vertical. The mass of the bar is 4kg . The displacement of bar when ball reaches the other extreme position (in m) is

A mass of M kg is suspended by a weightless string. The horizontal force required to displace it until string makes an angle of 45^@ with the initial vertical direction is:
