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
