A mass of 2kg is suspended with thread AB (Fig. 5.5). Thread CD of the same type is attached to the other end of 2 kg mass. Lower thread is pulled gradually, harder and harder in the downward direction so as to apply force on AB. Which of the threads will break and why?
This is a Short Answer type Questions as classified in NCERT Exemplar
Explanation- The thread AB will break earlier than the thread CD. This is because force acting on thread CD= applied force and force acting on thread AB = applied force +weight of 2kg mass. Hence force acting on thread Ab is larger than the force acting on thread CD
