A charged particle is whirled in a horizontal circle on a frictionless table by attaching it to a string fixed at one end. If a magnetic field is switched on in the vertical direction, the tension in the string

A stone with a mass of 0.9 kg is attached to one end of a string 0.8 m long. The string will break if its tension exceeds 500 N. The stone is whirled in a horizontal circle on a frictionless table top. The other end of the string is kept fixed. Find the maximum speed of the stone, it can attain without breaking the string.

A stone tied to a string of length l is whirled in a horizontal circle at a constant angular speed omega in a circle of radius r. If the string makes an angle theta with vertical then the tension in the string is :

A particle of mass m and charge Q is attached to a string of length l. It is whirled in a vertical circle in the region of an electric field E as shown in the figure-5.105.What is the speed given to the particle at the point B,so that tension in the string when the particle is at A is ten times the weight of the particle?

A particle of mass 14 g attached to a string of 70 cm long is rotated in horizontal circle. If the period of revolution is 2 sec, find the tension in the string.

A particle tied with a string is whirled along a vertcial circle.

An object of mass 10kg is whirled round a horizontal circle of radius 4m by a revolving string inclined 30^(@) to vertical. If the uniform speed of the object is 5 m//sec, the tension in the string (approximately) is
