Question

A 2 kg book is sitting on a table. A 10 N force is pulling it to the right. A 3 N force is pulling to the left. What is the Net Force acting on the book? A. 2 N down B. 7 N to the right C. 13 N to the right D. 15 N to the right

Answer 1

The net force acting on the book is 7 N to the right, calculated by subtracting the 3 N force to the left from the 10 N force to the right. Option B

Step-by-step explanation:

The net force acting on the book is determined by subtracting the leftward force from the rightward force. Since there is a 10 N force pulling to the right and a 3 N force pulling to the left, we calculate the net force as follows: 10 N - 3 N = 7 N to the right. This is the total force acting on the book after considering both the applied forces.

In accordance with Newton's second law, the net force is the vector sum of all the forces acting upon an object. If all forces are considered in the same dimension, the net force is simply the sum of all forces considering their direction. Therefore, for the book, the net force to the right is 7 N. Option B

Answer 2

Here's the 'vector equation' for that situation:

(10N right) + (3N left)

= (10N right) + (-3N right)

= 7N right .
