Question

A stone is tied to one end of a string. Holding the other end, the string is whirled in a

horizontal plane with progressively increasing speed. It breaks at some speed because

a) Gravitational forces of the earth is greater than the tension in string

b) The required centripetal force is greater than the tension sustained by the string

c) The required centripetal force is lesser than the tension in the string

d) The centripetal force is greater than the weight of the stone

explain with diagram if possible...! ​

Answer 1

Answer:

option C

Explanation:

In physics, tension is described as the pulling force transmitted axially

the centripetal force is the force that is pulling it inside

since the string breaks and moves tangencially, the tension increases and the centripetal force is reduced, which causes the breaking
