Assertion: Force of buoyancy due to atmo...

Assertion: Force of buoyancy due to atmosphere on a small body is almost zero(or negligible).
Reason: If a body is completely submerged in a fluid, then buoyant force is zero.

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:
C
Force of buoyancy,
`U=Vrho_(air)g`
since, `rho_(air)` is negligible. Hence, `U` is negligible.
