Distance

9: As a positive test charge being held close to a strong positively charged plate is released, the energy of the situation is becoming:

Kinetic

Potential

Heat

Chemical

10: If a proton in an electric field moves opposite the direction of an electric field line, the electric field does ______ work on the proton.

No

Positive

Negative

None of the above

Answer 1

#8

This question doesn't make sense to me.  It seems like it should say the energy is equal to the product of the change in potential and charge  (so if it was really phrased wrong, the answer should be charge).

#9

The positive charge would start moving away from the positively charged plate, so the energy is becoming kinetic.

#10

The electric field is slowing the proton down, so it is doing negative work on it.
