Question

a student pushes a 12 n book to the right with a force of 10 n. the book experiences a frictional force of 3 n. the free - body force diagram below represents the forces acting on the book. what is the magnitude of the net force acting on the book? a 7n b 11n c 13n d 37n

Explanation:

Step1: Analyze vertical forces

The vertical forces are \(12\,\text{N}\) (upward) and \(12\,\text{N}\) (downward). Since \(12 - 12=0\,\text{N}\), the net vertical force is \(0\,\text{N}\).

Step2: Analyze horizontal forces

The horizontal forces are \(10\,\text{N}\) (to the right) and \(3\,\text{N}\) (to the left). The net horizontal force is \(10 - 3 = 7\,\text{N}\).

Answer:

A. \(7\,\text{N}\)
