A hydrogen atom consists of a single proton and a single electron. If the distance between the proton and the electron were doubled, the electric force would be

1) 1/4 as much,
2) 1/2 as much,
3) twice as much,
4) not enough information to say,

and if instead the distance between the electron and proton were halved, the electric force would be
5) 1/4 as much.
6) 1/2 as much.
7) twice as much.
8) four times as much.
9) not enough information to say

Question 2

Ohm's law tells us that the amount of current produced in a circuit is

1) directly proportional to voltage.
2) inversely proportional to resistance.
3) both of these

which means that current in a conductor can be increased by
4) increasing the voltage across it.
5) reducing its resistance.
6) both of these
D) none of the above
