    Static friction is the friction that exists between two or more solids that are not moving with a relative speed. To calculate the static friction coefficient we use the formula Fs=us * n where Fs is the static friction, us is the coefficient of static friction and the n is the normal force.

    thus the coefficient of static friction will be 5 N: 25 N = 0.2

    Hence 0.2 is the coefficient of static friction
