A jagged line represents a resistor .
The answer would be "velocity will stay in the same direction." Since the ball is going in the same the ball is still going straight but just right. Many people get confused over velocity and speed, speed it the average amount on how fast a object is going and velocity is the amount of force a object has when it has speed. So, in this case since how the ball is going straight but just right it would stay in the same direction.
Hope this helps!
Answer:
Twice the initial value
Explanation:
Let the current be = I
the width of the conducting strips be = a
We know that magnetic field between two plates is given by

If the direction of this magnetic field is same between the two plates, then

= 0
And when the currents runs opposite at each plate, then


Hence the magnetic field will be twice the initial value of the magnetic field that runs between the plates.
