NEET Physics Mechanical Properties of Fluids Questions Solved


When a large bubble rises from the bottom of a lake to the surface. Its radius doubles. If atmospheric pressure is equal to that of column of water height H, then the depth of lake is

(a) H                                  (b) 2H

(c) 7H                                (d) 8H

(c) P1V1=P2V2(P0+hρg)V =P0×8V

Where h = depth of lake

hρg=7P0h=7×Hρgρg=7H
