Calculate Coefficient of Friction for a 200kg Load on a Horizontal Plane

Homework Statement

A load of 200kg rests on a horizontal plane.A horizontal force of 196N is needed to overcome friction.Find the coefficient of friction

F(gravity)=W=mg
F(friction)= (mu)N

W=mg
W=200(9.8)=1960N
This then is the F(normal) also.

Now
F(fric)=(mu)N
196=(mu)1960
mu=196/1960=0.2=answer

thanks in advance

Thanks for all the help.Yes, it was a typo...i know it should be 0.1 :)
