A particle is rotated in a vertical circle by connecting it to a string of length `l` and keeping the other end of the string fixed. The minimum speed of the particle when the string is horizontal for which the particle will complete the circle is

A particle is rotated in verticla circle by connecting it to string fixed. The minimum speed of the particle when the string is horizontal for which the particle will complete the circle is

A particle of mass m is rotated in a vertical circle by means of a string . The differnce in the tensions in the string at the bottom and the top of the circle would be

A stone of mass m tied to a string of length l is rotated in a circle with the other end of the string as the centre. The speed of the stone is v. If the string breaks, the stone will move

A body is moving in a vertical circle of radius r such that the string is just taut at its highest point. The speed of the particle when the string is horizontal is

A stone of a mass m tied to a string of length /is rotated in a circle with the other end of the string as the centre. The speed of the stone is V. If the string breaks, the stone will

A particle of mass m is tied to a string of length L and whirled into a horizontal plan. If tension in the string is T then the speed of the particle will be :

A body is moving in a vertical circle of raius 2r such that, the string is just taut at its highest point. The speed of the particle when the string is horizontal, is

A mass m is tied to a string of length l and is rotated in a vertical circle with centre at the other end of the string. (a) Find the minimum velocity of the mass at the top of the circle so that it is able to complete the circle. (b) Find the minimum velocity at the bottom of the circle corresponding to the above condition.

A particle of mass m is fixed to one end of a light rigid rod of length l and rotated in a vertical ciorcular path about its other end. The minimum speed of the particle at its highest point must be
