At some distance from a point charge, the electric potential is $600.0 \mathrm{V}$ and the magnitude of the electric field is $200.0 \mathrm{N} / \mathrm{C}$. Determine the charge and the distance from the charge.

Key Concepts

Coulomb's Law

Coulomb's law governs the interaction between charged particles, stating that the electrostatic force between two point charges is directly proportional to the product of their charges and inversely proportional to the square of the distance separating them. This fundamental principle not only explains the behavior of forces between static charges but also underlies the derivation of formulas for both electric potential and electric field.

Electric Potential

Electric potential is the potential energy per unit charge at a point in an electric field, typically expressed in volts. It represents the work done by an external force in bringing a unit positive charge from infinity to that point, without acceleration. In the context of point charges, it depends inversely on the distance from the charge, following an inverse relation as given by the formula V = kQ/r.

Electric Field

The electric field is a vector field representing the force per unit charge exerted on a test charge placed at a given point in space, measured in newtons per coulomb (N/C). For a point charge, the electric field magnitude decreases with the square of the distance from the charge, following the formula E = kQ/r².

Relationship Between Electric Potential and Electric Field

The electric potential and the electric field are closely related; the electric field is the negative gradient of the electric potential. In cases of radial symmetry such as a point charge, this relationship simplifies to the electric field being the potential difference per unit distance (E = V/r), linking how changes in potential relate to the magnitude of the field at different distances.
