Question

A stone is tied to the middle of a string and suspended from one end as shown in the given figure. Here S is the stone and O is the point of suspension. If we increase the pull at P gradually, the string will break.

A) Below the stone.
B) At the point P itself.
C) Above the stone.
D) Not can be decided.

Answer 1

Hint:The tension on a body always acts away from the body and the tension in any body is equal and opposite to the weight of the body that the string is hung with and if we increase the force then the tension has to also increase.

Complete step-by-step answer:
It is given in the problem that a stone is tied to the middle of a string and suspended from one end as shown in the given figure, where S is the stone and O is the point of suspension and the force at the point P is increased gradually and the string breaks and we need to find at which point the string will break.
It is given in the problem that the force exerted at point P is gradually increasing and as the force is gradually increasing then therefore there is enough time as the same tension is developed in the string on the other side of the stone. So when breaking stress acts on the string then the stress acts above the stone and the string breaks from above the stone.
The string breaks from above the stone.

The correct option for this problem is option C.

Note:Initially the tension in the string was equal to the weight of the stone but as the force on the string is increased then the tension on the string also increases and the string breaks because the string cannot withstand that much amount of load on as the load is above the strength of the string.
