Question
A block of mass of 10 kg lies on a rough inclined plane of inclination θ = sin-1
with the horizontal when a force of 30 N is applied on the block parallel to and upward the plane, the total force exerted by the total on the block is nearly along (coefficient of friction is μ =
) (g =10m/s2)


Options
A.OA
B.OB
C.OC
D.OD
Solution
fmax = μN =
(80) = 60

Total force external by the plane
