QUESTIONS 4. What is the coefficient of static friction between a load of mass 2kg and a horizontal surface, if the limiting frictional force is I0N. 

Ans:0.5 NECO 2000.

SOLUTIONS 

Frictional force F = 10N

Mass = m = 2kg

Coefficient of static friction μ, = ?

W = R = mg = 2 x 10 = 20N

F = μR

μ = F/R

μ = 10/20

μ = 1/2 = 0.5 ANSWER
