Question

Statement-1: A partly filled test tube is floating in a liquid as shown. The tube will remain as if its atmosphere pressure changes. 

Statement-2: The buoyant force on a submerged object is independent of atmospheric pressure.

(A) Statement-1 is true, statement-2 is true and statement-2 is the correct explanation for statement-1

(B) Statement-1 is true, statement-2 is true and statement-2 is NOT the correct explanation for Statement-1 

(C) Statement-1 is true, statement-2 is false. 

(D) Statement-1 is false, statement-2 is true 

Answer 1

Correct Option (D) Statement-1 is false, statement-2 is true

Explanation:

Pressure inside the tube is P = P₀ + ρgh When pressure changes height will also change. 

So statement 1 is true. 

Buoyant force is independent of atmospheric pressure.
