The magnitude of the frictional force is f = μ * 4.9 N.
What is magnitude?
Magnitude is a term used in physics to describe an object's maximum size and direction. Scalar and vector quantities both use magnitude as a common factor. We are aware that scalar quantities are those that have only magnitude by definition. Those quantities with both direction and magnitude are considered vector quantities. An earthquake's size is measured in terms of its length, breadth, and width. It is calculated based on the earthquake's actual size. A single magnitude is thought to exist for an earthquake. Due to variables like the type of material surface and distance from the epicentre, the magnitude of the shaking brought on by the earthquake varies depending on where it occurs.
The frictional force between the book and the surface is the resistive force pushing back against the pushing force of 6N. The magnitude of this resistive force depends on the coefficient of friction between the book and the table surface, as well as the normal force, which is equal to the weight of the book (0.50 kg * 9.8 m/s2 = 4.9 N).
The magnitude of the frictional force (f) can be calculated using the equation f = μ * N, where μ is the coefficient of friction and N is the normal force. Thus, the magnitude of the frictional force is f = μ * 4.9 N.
