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.

2.

In the above Question, if the string C is stretched slowly,
then

1The portion AB of the string will break
2The portion BC of the string will break
3None of the strings will break
4None of the above

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

3.

penetrates the wooden block upto 6 cm. Then the average
force imposed by the bullet on the block is

18300 N
2417 N
