Solution

The net force on the box sitting on the floor can be represented as zero. Here's why:

  1. The box is not moving, which means it's in a state of equilibrium. In physics, an object is in equilibrium when the net force acting on it is zero.

  2. There are two forces acting on the box. The first is the force of gravity, which pulls the box downwards. This force can be calculated by multiplying the mass of the box by the acceleration due to gravity.

  3. The second force is the normal force, which is the force exerted by the floor on the box. This force acts upwards and is equal in magnitude and opposite in direction to the force of gravity.

  4. Since these two forces are equal and opposite, they cancel each other out, resulting in a net force of zero.

So, the net force on the box can be represented as zero.
