When a stone is tied to a string whirled in a vertical circle?
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 its lowest position and has a speed u. The magnitude in its velocity as it reaches a position, where the string is horizontal, is.
When a stone is rotated in a circle by a string?
Complete answer: The only connection to the stone is the string so, if it is performing circular motion in a horizontal circle then whatever the horizontal force it has to be present in the string. So when an object performs circular motion then along the radial direction there will be centripetal force acting.
When a stone tied to a string is?
The correct answer is the stone flies off tangentially. A stone tied to a string is whirled in a circle. As it was revolving, the rope suddenly snaps. Then the stone flies off tangentially.
Is tied to a string of length L?
What happens to a stone tied to the end of a string and whirled in a circle if the string suddenly breaks explain why?
What happens to a stone tied to the end of string and whirled in a circle if the string suddenly breaks? If the string suddenly breaks, the stone will fly off tangentially along the straight line due to inertia of direction. This is because, the velocity at any point is directed along the tangential at that point.
What is the direction of motion of a stone revolving with the help of string is cut from the string?
radially outward
The stone moves radially outward.
When a stone is tied to the end of a string and whirled in a circle if the string suddenly breaks then?
When a stone is tied at the end of a string and whirled in a circular path holding its other end in the hand 1 i the centripetal force is provided by?
The direction of acceleration of stone is towards the centre of the circular path. Force of tension in the string provides the centripetal force required for circular motion.
What will be the work done by the tension in the string when a stone is tied to a string and whirled in a circle?
Work done by the stone is zero. Here, in circulation path displacement is zero.
When a stone is tied to a string and whirled in a circular path then the displacement of the stone is to the circular path?
What happens to a stone tied to the end of a string?
When a stone is tied to the end of the string and whirled in a circle if the string suddenly breaks then?
When a stone is moving around a circular path, its velocity acts tangent to the circle. When the string breaks, the centripetal force will not act. Due to inertia, the stone continues to move along the tangent to circular path, and flies off tangentially to the circular path.
