Question

The magnitude of the frictional force along the plane is most nearly​

Answer 1

Answer:

F = N*μ or F =m*g*μ

Explanation:

The friction force is defined as the product of the normal force by the corresponding friction factor.

When a body is in equilibrium over a horizontal plane its normal force value shall be equal to:

$N = m*g\\where:\\m=mass [kg]\\g=gravity [m/s^2]\\N= normal force [N]$

if we simplify this formula more for a balanced body on a horizontal plane, we will have.

$F=m*g*u$
