As shown in figure BEF is a fixed vertical circular tube. A block of mass m starts moving in the tube at point B with velocity V towards E. It is just able to complete the vertical circle. Then.

In a vertical circle of radius r , at what point in its path a particle has tension equal to zero if it is just able to complete the vertical circle

In the figure ADB & BEF are two fixed circular paths. A block of mass m enters in the tube ADB through point A with minimum velocity to reach point B . From there it moves on another circular path of radius R '. There it is just able to complete the circle.

A particle of mass m attached to an inextensible light string is moving in a vertical circle of radius r. The critical velocity at the highest point is v_( 0) to complete the vertical circle. The tension in the string when it becomes horizontal is

A particle of mass m attached to an inextensible light string is moving in a vertical circle of radius r. The critical velocity at the highest point is v_( 0) to complete the vertical circle. The tension in the string when it becomes horizontal is

As shown in figure, a particle of mass m is performing vertical circular motion. The velocity of the particle is increased, then at which point will the string break?

What is the apparent weight of a boby of mass m at (a) the highest and (b) lowest point if it is just looping the loop in a vertical circle ?

A uniform rod of mass m and length / is hinged at upper end. Rod is free to rotate in vertical plane. A bail of mass m moving horizontally with velocity vo collides at lower end of rod perpendicular to it and sticks to it. The minimum velocity of the ball such that combined system just completes the vertical circle will be

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.
