Questions
A block rest on a rough inclined plane making an angle with the horizontal. The coefficient of static friction between the block and plane is 0.8. If the frictional force on the block is 10N, the mass of block is ()
detailed solution
Correct option is C
if μ is 0.8 angle of inclination is less than angle of repose and it is stationary frictional force is eaual to applied force = mgsinθ=10 m(10) 0.5=10 m=2Talk to our academic expert!
