Question

Two sphere A and B are placed between two vertical walls as shown in figure. Draw the free body diagrams of both the spheres.

Answer 1

As shown in figure,

FBD of sphere 'A' ,

$N$= Normal Reaction exerted by ground,

$w_1$= Weight of the body,

$R_1$= Normal Reaction exerted by side wall,

$N_{BA}$= Normal reaction exerted by sphere 'B',

FBD of sphere 'B' ,

$w_2$= Weight of the body,

$R_2$= Normal Reaction exerted by side wall,

$N_{AB}$= Normal reaction exerted by sphere 'A',
