Question

A mass of 1 kg is suspended by a string A. Another string C is connected to its lower end (see figure). If a sudden jerk is given to C, then (A) the portion A B of the string will break (B) the portion B C of the string will break (C) none of the strings will break (D) the mass will start rotating

When a sudden jerk is given to C, an impulsive tension exceeding the breaking tension develops in C first, which breaks before this impulse can reach A as a wave through block.

Q. A mass of $1 k g$ is suspended by a string $A$ . Another string $C$ is connected to its lower end (see figure). If a sudden jerk is given to $C$ , then

the portion A B of the string will break

the portion B C of the string will break

none of the strings will break

the mass will start rotating
