Question

what is the formula of force of friction

Answer 1

Frictional force is given as
F= mew ×R
Where R is reaction
R =mg
Ie F=mew mg
Where mew=coefficient of static friction

Answer 2

Answer:

Explanation:

To calculate the frictional force  , use the given formula :

F (f) =   μ ×  F (n)

Where , F (f) is the magnitude of friction, μ is the coefficient of friction &

F(n) is the magnitude of normal force respectively..
