A mass of 1 kg is suspended by a string ...

A mass of 1 kg is suspended by a string A. another string C is connected to its lower end (see figure). If the string C is stretched slowly, then

A

The portion AB of the string will break

B

The portion BC of the string will break

C

None of the strings will break

D

none of the above

Text Solution

Verified by Experts

The correct Answer is:

A

When the spring C is stretched slowly, the tension is A is greater than that of C, because of the weight mg and the former reaches breaking point earlier.
