Assertion : A wooden plank is floating in two liquids as shown. Net force applied by liquid-1 on plank is zero.
Reason : Contribution in upthrust due to liquid -1 is `V_(1)rho_(1)g`. Where `V_(1)`= volume immersed in liquid -1 and `rho_(1)` is the is the density of liquid -1.

A

If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.

B

If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

C

If Assertion is true but Reason is false.

D

If Assertion is false but Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
