It is much easier to burst an inflated balloon with a needle than
by a finger because of the following reason:
---> The tip of the needle is sharp so that due to its sharp tip, the needle may put force on very small area of balloon , producing a large pressure sufficient to pierce the balloon .
where as ,
-->if we use finger to burst balloon, the surface area of it is more and blunt . Hence less pressure will act on balloon which is not sufficient to burst it.

Answer:
as because the needle has less area compared to finger thus we know pressure is inversely proportional to area so the pressure will be more and the balloon will burst easily
