Question

it is much easier to burst an inflated balloon with a needle than by a finger.explain

Answer 1

The needle is sharp and is pinpointed. So when it is used to burst the balloon it exerts larger pressure on the balloon.

This larger pressure makes the balloon to burst whereas the area occupied by a finger on the balloon is more and it is blunt. Bursting the balloon with fingers can harm human life and we should avoid such experiments.

This is because the point of the needle is Sharp and when the point of the needle is pointed then the force is exerted in Large quantity.



Wherever we point the finger then the force exerted is less. and when we exert the finger then that time the force is less.
