The difference in tensions in the string at lowest and highest points in the path of the particle of mass 'm' performing vertical circular motion is :

A particle (bob) of mass 1 kg is performing vertical cicular motion. Then :

A particle performing uniform circular motion has

For a particle performing a uniform circular motion the acceleration is

A particle is performing uniforme circular motion, has constant

The maximum velocity at the lowest point, so that the string just slack at the highest point in a vertical circle of radius l.

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 stone of mass 0.3 kg is tied to one end of a string 0.8 m long and rotated in a vertical circle. At what speed of the ball will the tension in the string be zero at the highest point of the circle? What would be the tension at the lowest point in this case ? Given g = 9.8 ms^(-2) ?
