Question

It is much easier to burst an iflated balloon with a needle than by a finger.Explain

Answer 1

we know that pressure =force/area . a needle has less surface area than our finger thus needle much higher pressure so it is easy to burst an inflated balloon with a needle.

Answer 2

A needle has a smaller surface area than a finger. So, by applying a small amount of pressure, a larger amount of force could be produced in a needle as compared to that of the finger. That is why it is easier to burst an inflated balloon by a needle than by a finger.
