Some question (Assertion-Reason type) are given below. Each question contains STATEMENT-1(Assertion) and STATEMENT-2(Reason) . Each question has 4 choices (A),(B),(C ) and (D) out of which ONLY ONE is correct. So select the correct choice :
STATEMENT-1
1kg of cotton fibre will weight less lens in air when made more fluffy.
STATEMENT-2
Weight of air in cotton will cancel out with the force of extra buoyancy acting on it.

A

Statement-1 is True, Statement-2 is True, Statement-2 is a correct explanation for Statement-1.

B

Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-1.

C

Statement-1 is True, Statement-2 is False.

D

Statement-1 is False, Statement-2 is True.

Text Solution

Verified by Experts

The correct Answer is:
D
Weight of fluffy cotton will include the weight of air trapped in it. It will however exactly cancel out by the extra buoyant force acting on the trapped air.
