Answer 2

Since we know that pressure is equal to force upon area this means as the area increases pressure decreases because pressure is inversely proportional to area.

$pressure \: = \: \frac{force}{area}$

$pressure \: is \: \\ directly \: proportional \: to \: \frac{1}{area}$

$i.e. \: pressure \: is \: \\ inversely \: proportional \: to \: area$

Therefore,

Our finger have much larger area than the tip of a pencil. This, larger area causes decrease in pressure and so our finger does not burst the balloon but the tip of a pencil does.

Hope I explained you and cleared your doubts.
