Question

An inflated balloon bursts if you slightly push it's surface with the pointed tip of a pencil. However, it does not burst if you push it gently with your finger. Why?

Answer 1

Always when surface area of the object is lesser, the pressure is greater and when surface area of the object increases, the pressure decreases .

So when we use the pencil ,that balloon bursts but not in the case of when we use our fingers.

(Hint - pressure = thrust/area)

Answer 2

Answer:

? when we push its surface with our finger, the surface area in contact with its surface is more so ultimately pressure will be less and balloon does not burst & when we push it with pointed tip of pencil, the surface area in contact with its surface is less and pressure is more and balloon bursts out !!!!!!
