Consider the following two statement

\mathrm{A}

and

\mathrm{B}

, and identify the correct choice in the given answers

A : The excess pressure inside a small liquid drop is more than that of a big drop.

B : As the aeroplane moves fast on the runway for take off the pressure is more on the upper surface of its wings and less on the bottom surface of the wings.

View answer and explanation

Correct option: B

A is true but B is false

Option B is correct. Excess pressure inside a small liquid drop is indeed more than that of a big drop, but the pressure on the upper surface of an airplane wing is less than the bottom surface.
