Question

If an object is being pulled by two forces, one 4 N to the left and the other 2 N to the right, what is the net
force acting on the object?

Answer 1

Answer:

2N

Explanation:

subtract  rthe two forces to see which is greater

4-2=2

Answer 2

Since this object is being pulled by two forces, the net  force acting on the object is 2 Newton, to the left.

• Let the first force be A.

• Let the second force be B.

Given the following data:

• Force A = 4 Newton, to the left.

• Force A = 2 Newton, to the right.

To find the net  force acting on the object:

A net force can be defined as the vector sum of all the forces that are acting on a physical object or body.

This ultimately implies that, a net force is a single (one) force that substitutes the effect of all the forces acting on a physical object or body.

Mathematically, net force is given by the following:

$Net \;force = F_1 + F_2 + F_3 + F_4 + .....F_n$

Where:

• F represents each force.

In this scenario, the forces are acting in opposite directions (left and right) and as such, we would subtract the two forces:

$Net\;force = F_A - F_B\\\\Net\;force = 4 - 2$

Net force = 2 Newton, to the left.

Note: The direction is to the left because Force A has more magnitude than Force B, so the object would be pulled to the left.
