The limiting frictional force is 50 N.
Frictional force is the force that opposes motion. The frictional force acts in a direction that is opposite to the force moving the body forward.
The weight of the object is given by;
W = mg
W = 10 Kg × 10 ms-2 = 100 N
Now;
Recall that;
μ = F/R
μ = coefficient of friction
F = limiting frictional force
R = reaction force
Reaction = weight = 100 N
0.5 = F/100 N
F = 0.5 × 100 N
F= 50 N
