1any one////
since the botom surface of cylinder is in liquid B then how can buoyant force can be aplied by liquid A on cylinder in upward direction as no bottom surface is in liquid A ?
also it views that liquid A will apply force from top surface in downward direction, since force act always perpendicular to body surface then why in books in this question a buoyant force of liquid A is in upward direction ?
pls give explanation

11actualy buoyant force is related to pressure.u r correct tht there ll b force henc pressure only at bottom.and ths pressure z not only due to lower liquid but due to both liquids.due to ths pressure there ll b force on the bottom
3actually here the liquid A applies the buoyant force on liquid b....and then the liquid b applies the cumulative buoyant force on the body...its like the liquid a applies the buyant force not directly but through the liquid b...hope now its clear....
1the net upward force on cylinder by the liquids is buoyant force.
net upward force is due to pressure applied by liquid B on its lower surface .
due to presence of A pressure at this lower surface is increased .
mathematically calculated the resultant upward force comes out to be equal to buoyant force by A+ by that by B. i.e suppose is that much part of the body is submerged in A then how much buoyant force it would exert.
