A mass of \(1 \mathrm{~kg}\) is suspended by a string \(A\). Another string \(C\) is connected to its lower end as shown in figure. If a sudden jerk is given to \(C\), then
- A the mass will start rotating
- B the portion \(A B\) of the string will break
- C the portion \(B C\) of the string will break
- D None of the string will break
Answer & Solution
Correct Answer
(C) the portion \(B C\) of the string will break
Step-by-step Solution
Detailed explanation
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.
