Answer to Question #78105 in Mechanics | Relativity for Raj

Question

A block of ice, iron and wood (all cubical) of the same mass are left at the top of an inclined plane. Assume that the incline is such that all 3 start moving. Which of them experience greater frictional force and why?

Answer 1

Force of friction depends on normal reaction of the surface and on coefficient of friction. For all these bodies normal reaction is the same because they has equal masses. So we can make a conclusion that they all will experience the same force of friction.
