After the ball reaches the top and begins its return back down, it's just a falling object that's been dropped.
The amount that its downward speed increases every second is just the acceleration of gravity on Earth.
That's <em>9.81 meters per second</em> every second.

Explanation:
If the beam is in a magnetic field, a simple check is to rotate the CRT a quarter of a turn. If the beam is to the right, a magnetic field should be produced. This is because a magnetic field would be up or down that will allow the beam to be pushed to the right or left. In conclusion, if turning the CRT a quarter of a turn, nothing should happen because the CRT is perpendicular to the magnetic field.
A check to see if the beam is in an E field, you should rotate the CRT a quarter of a turn and see if the beam is centered. If you turn the CRT again another quarter of a turn and see if the beam is bent in the opposite direction. If both tests are true, then the CRT must be in an E field. Otherwise, the CRT will be broken.
