Physics - NLM Question with Solution | TestHub

If ${\mu }_A>{\mu }_B$ then contact force depends on mass as well as angle of inclination of inclined plane.

In every condition contact force depends on mass and the inclination of the inclined plane

If ${\mu }_A={\mu }_B$ then contact force between the blocks is zero

If ${\mu }_A={\mu }_B=0$ then contact force between them will be zero
