A stone tied to a string of length `L` is whirled in a vertical circle with the other end of the string at the centre. At a certain instant of time the stone is at lowest position and has a speed `u` . Find the magnitude of the change in its velocity as it reaches a position, where the string is horizontal.

A stone is tied to a string of length l and is whirled in a vertical circle with the other end of the string as the centre. At a certain instant of time, the stone is at its lowest position and has a speed u. The magnitude of the change in velocity as it reaches a position where the string is horizontal (g being acceleration due to gravity) is

A stone tied to a string of length L is whirled in a vertical circle with the ofter end of the string at the centre . At a certin instant of time , the stone is at its lowest position , and has a speed is , the magintube of the change in its velocity as it reached a positive when the string is horizontal is

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 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 stone is tied to the end of a string of length 1 and whirled in a horizental circle. When the string breaks then stone

If a bodyy is tied to a string and whirled in vertical circle, then the tension in the string at the highest position is

A pendulum bob is rotated in a vertical circle with one end of string of length l fixed at a position . At a certain instant bob is at its lowest position and is moving with speed u . Calculate the magnitude of change in velocity when string becomes horizontal for a moment .
