Question

When we rotate a ball which has a string attached to it it goes away from us . why?if centripetal force is acting on it isn't it is supposed to come near us . plz tell no google . explain it in short class 11 and 12 students

Answer 1

Answer:

consider a small sized ball moving around in a circle at a constant speed while Tide to a piece of string looped around a central peg . For this circular motion , the ball requires a centripetal force which is provided by the tension force T developed in the string .

If the string is cut from middle , then the tension ceases and consequently , the ball slides off in a straight path along the tangent due to its directional inertia.
