A small spherical ball is suspended through a string of length `l`. The whole arrangement is placed in a vehicle which is moving with velocity `v`. Now suddenly the vehicle stops and ball starts moving along a circular path. If tension in the string at the highest point is twice the weight of the ball then

A small spherical ball is suspended through a string of length l . The whole arrangement is placed in a vehicle which is moving with velocity v . Now, suddenly the vehicle stops and ball starts moving along a circular path. If tension in ht estring at the highest pointn is twice the weight of the ball then (assume that the ball completes the vertical circle)

A ball B is suspended from a string of length l attached to a cart A, which may roll on a frictionless surface. Initially the cart is at rest and the ball is given a horizontal velocity v_(0) . Determine the maximum height reached by the ball.

A ball of mass m is suspended by a thread of length l. With what minimum velocity has the point of suspension to be shifted in the horizontal direction for the ball to move along the circle about that point? What will be the tension of the thread at the moment it will be passing the horizontal position?

A small ball B of mass m is suspended with light inelastic string of length L from a block A of same mass in which can move on smooth horizontal surface as shown in the figure. The ball is displaced by angle theta from equilibrium position and then released. Tension in string when it is vertical, is

From the roof of a train, a metal ball is suspended by a string. When the train moves with uniform velocity, will the string remain vertical?

A small positively charged ball of mass m is suspended by an insulating thread of length L. This ball remains in equilibrium with string horizontal when another small charged ball is placed exactly at a distance L below the point of suspension of the first ball. The second ball is slowly moved away from the first ball to a far away point. (The second ball is moved horizontally so that the first ball does not accelerate). As a result the first ball lowers down to the original position of the second ball and the string become vertical. Find the work done by the external agent in removing the second ball.
