The force per unit charge is known as

The correct answer is Electric field.

Key Points

• The electric field is defined as the force experienced per unit positive charge at a point in space.
• It is a vector quantity, represented by the symbol E, and is measured in units of newtons per coulomb (N/C) or volts per meter (V/m).
• The formula for the electric field is E = F/q, where F is the force experienced by the charge and q is the magnitude of the charge.
• The direction of the electric field is the direction of the force experienced by a positive test charge placed in the field.
• Electric fields are produced by charged objects, and their strength diminishes as the distance from the charge increases.

Additional Information

• Electric Potential:
  • Electric potential is the work done in bringing a unit positive charge from infinity to a point in an electric field.
  • It is a scalar quantity and is measured in volts (V).
  • The relationship between electric field and electric potential is given by E = -dV/dx, where dV is the change in potential and dx is the distance.
• Electric Current:
  • Electric current is the flow of electric charge in a conductor, typically measured in amperes (A).
  • It is defined as the rate of flow of charge, expressed as I = Q/t, where Q is charge and t is time.
• Electric Force:
  • Electric force is the force exerted between two charged objects, governed by Coulomb's law.
  • Coulomb's law states that the force is directly proportional to the product of charges and inversely proportional to the square of the distance between them.
• Field Lines:
  • Electric field lines are imaginary lines that represent the direction and strength of the electric field.
  • These lines originate from positive charges and terminate at negative charges.
  • The density of field lines indicates the strength of the electric field.
