  • 2. 2Everything Science lawCoulomb’s law describes the electrostatic force between two point charges and can be statedas: the magnitude of the electrostatic force between two point charges is directly proportionalto the product of the magnitudes of the charges and inversely proportional to the square ofthe distance between them.The proportionality constant k is called the electrostatic constant and has the value:F=kQ1Q2r29×109N⋅m2⋅C−2
  • 3. 3Everything Science fieldsAn electric field is a region of space in which an electric charge will experience a force. Thedirection of the field at a point in space is the direction in which a positive test charge wouldmoved if placed at that point.We can represent the electric field using field lines. By convention electric field lines pointaway from positive charges (like charges repel) and towards negative charges (unlikecharges attract).
  • 4. 4Everything Science field lines
  • 5. 5Everything Science field: magnitudeThe magnitude of the electric field, E, at a point can be quantified as the force per unit chargeWe can write this as:where F is the Coulomb force exerted by a charge on a test charge q. The units of the electricfield are newtons per coulomb orSince the force F is a vector and q is a scalar, the electric field, E, is also a vector; it has amagnitude and a direction at every point.E=FqN⋅C−1
