Question

Assertion : Smaller drops of liquid resist deforming forces better than the larger drops.

Answer 1

(c) A is true but R is false

Explanation :

The excess pressure inside the small drop is large as compared to the large drop because of which smaller drop of liquid resists deforming force better than the large drop.

Excess pressure = 2T/r

where T = surface tension

r = radius of liquid drop.

Therefore excess pressure is inversely proportional to its radius and hence the surface area.
