If the distance between two charged particles is doubled, the strength of the electric force between them will __________.
If the distance between two charged particles is doubled, the strength of the electric force between them will __________.
Coulomb's law gives the relationship between the force of an electric field and the distance between two charges:
The strength of the force will be inversely proportional to the square of the distance between the charges.
When the distance between the charges is doubled, the total force will be divided by four (quartered).

A capacitor with capacitance 
is constructed by putting a thin piece of cardboard between two copper plates, then each plate is connected to a battery. If the copper plates are cut in half then what is the effect on the capacitance of the circuit?
A capacitor with capacitance
Capacitance of a circuit is defined by the equation:
Where 
is the capacitance, 
is a constant of nature, 
is the area of the capacitor, and 
is the distance between the two plates
Since the metal plates are cut in half, the area is halved. We can substitute 
in for 
The result is that the capacitance is half the original quantity.
