Questions
In Figure, coefficient of kinetic friction between the 4 kg block and the inclined surface is . Here 'm' is such a mass that the 4 kg block is moving up the plane with a constant speed, then m is:
detailed solution
Correct option is D
Net force on system of two blocks = 0= mg = 4gsin 30° + μ(4gcos30°) = m = 4 kgTalk to our academic expert!
