Laws of motion important examination points

Equilibrium of bodies on a rough Inclined Plane:


Case I: When motion of body is downwards on the plane
















Case II: When motion of body is upwards on the plane  

















Motion of two bodies in contact on a smooth horizontal surface:

Case I: When force is applied on body with mass m1
















Case II: When force is applied on body with mass m2
















Three bodies in contact on a smooth horizontal surface
When three bodies are in contact with each other, Force F is applied
on the body with masses m1, m2, m3 is as shown in figure 









The action and reaction forces on the bodies is given as
