Questions
In Figure, coefficient of friction between the block and the floor is ''. Force F that will move the block on the floor with a uniform speed is
detailed solution
Correct option is D
Normal reaction N=mg+FcosθFor constant speed Fnet=0⇒Fsinθ−μN=0⇒Fsinθ−μ(mg+Fcosθ)=0⇒F=μmgsinθ−μcosθTalk to our academic expert!
