These questions consist two statements each, printed as Assertion and reason, while answering these question you are required to choose any one of the following four responsis:
(a) If both the assertion and reason are true and reason is a true explanation of the assertion.
(b) If both the assertion and reason are true but the reason is not the correct explanation of assertion.
(c ) If the assertion is true but reason is false.
(d) If both the assertion and reason are false.
Q. Assertion: A bubble comes from the bottom of a lake to the top.
Reason: Its radius increases.

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:
B
Since, the fluid move from higher pressure and in a fluid, the pressure increases with increase of depth. Hence the pressure `p_(0)` will be lasser at the top than that the bottom, `(P_(0)+hrhog)` . So the air bubble moves from the bottom to the top and does not move sideways coming from bottom to top the pressure decreases according to Boyle's law `PV` = constant.
Therefore, if pressure decreases the volume increses. it means radius increases.
