Question

You are given a bunch of electrons. Electrons have charge -e, but what does this mean?

a) The average charge of the electrons will be -e, with the actual charge distributed around -e

b) Most electrons will have charge of exactly -e, but some will have a charge that is slightly higher and some slightly lower

c) Regardless of conditions, all of the electrons have a charge of exactly -e

In electrostatic experiments, a constant concern is loss of charge to the environment or the accidental grouping of an object. In general, it is much harder to keep something charged than to get rid of charge. What aspect of the Law of Conservation of charge does this showcase?

a) Charge is constantly destroyed

b) Conservation of charge applies only to fundamental charged particles like the electrons, not to larger objects like rods or boards.

c) Charge is not destroyed, it is transferred to one body or another.

d) The effects of charge wear off over time to the point where they can no longer be observed.

e) The Law of Conservation of Charge is only an approximation of natural processes.

e) The reaction is fine as it stands; no additional particles are needed to complete the reaction.

Explanation / Answer

(c)Regardless of conditions, all of the electrons have a charge of exactly -e

charge conservation means that in elementary particle reactions that create charged particles, equal numbers of positive and negative particles are always created, keeping the net amount of charge unchanged.

c) Charge is not destroyed, it is transferred to one body or another.
