    Answer:

    Explanation:

    If there is only 1 force, the body can never be in equilibrium, providing that the force is not zero (and that would hardly be a force. Zero is possible in math and it means something. It is debatable in physics).

    You cannot think of a condition where something is stationary on planet earth and there are not 2 forces or more forces involved.

    Think of something like a block of wood sitting on a table. It is not moving, we’ll say. Gravity is holding it down, but what is pushing up on it?

    The table is. There are 2 forces and they are equal in magnitude, but opposite in direction. That matters.
