Question

If two forces are applied in opposite directions to move the cart with a force of 40 N each. In which direction will the cart move?

• A. The cart will move in the right direction.
• B. The cart will move in the left direction.
• C. The cart will move in the south-east direction.
• D. The cart will not move.

Answer 1

The correct option is D The cart will not move.

If two forces are acting in the opposite directions, then the net force is the difference between the magnitudes of two forces. Force applied by person A is 40 N whereas force applied by person B is also 40 N. Net force will be 40 N - 40 N = 0 N. As the forces being equal and opposite, the resultant or net force becomes zero. Thus, the cart will not move from its position.
