Statement I: Smaller drops of liquid resist deforming forces better than the larger drops.
Statement II: Excess pressure inside a drop is directly proportional to its surface area.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are truw but reason is not correct explanation of assertion
C. If assertion is true but reason is false
D. If both assertion and reason are false.

Answer

C

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.
