A 100 kg box is initially at rest on a level surface. One 10 N force acts on the box , directed toward the right. A second 10 N force acts simultaneously on the box , directed toward the left , as shown.

The box will not move because balanced forces are acting on it.

Explanation:

According to Newton's first law of motion, an object will remain in its state of rest or motion along a straight line unless acted upon by an unbalanced force.

An unbalanced force is an individual force acting on any side of an object which is not balanced by a force of equal magnitude acting in the opposite direction.

From the image, two forces of equal magnitude of 10 N are pulling the 100 kg box in opposite directions. Since the two forces, 10 N each are pulling the object in opposite directions, they are balanced forces. Therefore, the box will not move because balanced forces are acting on it.

the answer is d (apex) good luck : ))
