Question

Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): When a body is dipped in liquid, its weight decreases.
Reason (R): The decrease is due to higher density of displaced liquid.

• A. Both (A) and (R) are true and (R) is the correct explanation of (A).
• B. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
• C. (A) is true but (R) is false.
• D. (A) is false but (R) is true.
• E. Both (A) and (R) are false.

Answer 1

The Correct Option is B

Concept: Buoyancy principle.
Step 1: Check assertion.} Weight appears reduced → True (buoyant force)
Step 2: Check reason.} Reason is incorrect explanation (not density but upthrust force)
Step 3: Relation check.} Reason does not explain correctly.
Step 4: Final answer.} Thus, both true but incorrect explanation.
