Answer:
The card will remain stationary, and will not move.
Explanation:
The card will remain stationary, and will not move because the resultant force acting on the card is equals to zero.
To understand the concept of resultant forces, we can think of a tug of war game. The difference between the forces of the two opposite teams refers to the resultant. It is more like a force imbalance. The team with the higher force wins. If the forces of the teams are equal, the resultant force becomes zero and there is a stalemate.
The same happens in or physical system in which the dynamic card is pulled. Because the two forces pulling the card are equal and opposite, there is a stalemate, and they cancel out each other, thus making the card stationary.
