Assertion: Water is filled in a U-tube of different cross-sectional area on two sides as shown in figure. Now equal amount of oil `(RD=0.5)` is poured on two sides. Level of water on both sides will remain unchanged.

Reason: Same weight of oil poured on two sides will produce on two sides will produce dofferent pressure.

A

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

B

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

C

If Assertion is true, but the Reason is false.

D

If Assertion is false but the Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D

Area of cross-section is different. So, heights are different. In pressure height is more important.
