A metal block of mass 5kg lies on a rough horizontal platform. If a horizontal force of 8 N applied to the block through its center of mass just slides the block on the platform, then the coefficient of limiting friction between the block and the platform is: A 0.16 B 0.63 C 0.80 D 1.6 E 2.00.

  2. M*g = 5*9.8 = 49 N. = Wt. of block = Normal force,

    8-u*49 = 5*0.
    u = coefficient of friction = 8/49 = 0.16.

  5. Yes it is A.0.16
    Coefficient of friction =force/mass*acceleration due to gravity. That is 8/5*10 =O.16
