Q10.
Won't the answer be C??
Dear Student,
Excess pressure across a bubble is inversely proportional to the radius of the bubble, i.e.Δp is proportional to 1/r.
Value of r of the sub-hemispherical bubble is more than that for a hemispherical bubble
The excess pressure across the bubble at end 2 is less than that at end 1.
Hence, air from end 1 will flow towards end 2 resulting in a decrease in the volume of the bubble at end 1 .
Option A will be correct.
Regards
