The required force is 280 N.
We must subtract our individual forces in order to calculate the net force.
In general, whenever forces act on an object in opposite directions-the net force is equal to the difference between the two forces.
To calculate the net force, one force is subtracted from the other. therefore, here
325 N is force 1 to the right.
45 N is force 2 to the left.
Force 1 - Force 2 is the net force.
net force= 325N - 45N
net force= 280 N
So the required force is 280 N.
