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).

On which of the following does the amount of work required to move a charge in an electric field depend?
On which of the following does the amount of work required to move a charge in an electric field depend?
Work done by electric field is defined:
Notice that the only variable in the equation is the potential, so this is the only quantity on which work depends.
