These questions consist two statements each, printed as Assertion and reason, while answering these question you are required to choose any one of the following four responsis:
(a) If both the assertion and reason are true and reason is a true explanation of the assertion.
(b) If both the assertion and reason are true but the reason is not the correct explanation of assertion.
(c ) If the assertion is true but reason is false.
(d) If both the assertion and reason are false.
Q. Assertion: Smaller drops of liquid resist deforming forces better than the larger drops.
Reason: Excess pressure inside a drop is directly proportional to its surface area.

Answer

C

Explanation

Also excess pressure inside a bubble is
where R is radius of bubble. Since excess pressure is inversely proportional to radius, hence excess pressure inside a smaller drop is large as compared to larger drop due to which smaller drop resists deforming forces better than a larger drop
Also `P=(4T)/(R )=(4W)/(R.triangleA)` (`because` `T=(W)/(triangleA)`)
`impliesPprop(1)/(triangleA)`
Hence, excess pressure is inversely proportional to surface area.
