What is Coulomb’s Law?
What is k?
Formula for Coulomb’s Law?
What is the superposition principle?
What is electric charge?
A property of matter that experiences a force when next to other charges or in an electric field.
Unit: Coulomb (C)
What is electric field, 𝑬?
Region where charges experience a force. Electric field lines are drawn alway form positive and towards negative.
Unit: Newtonc/Coulomb (N/C)
General formula for electric field?
What is electric Force, F_e?
What values effect electric force?
What is electric field formula for field of a point charge?
What is continuous distribution?
What are electirc field lines?
Electric field line rules?
What is an electric dipole?
Two charges of the same magntitude but opposite signs at a small distance, d.
What is an electric dipole moment, 𝐩?
A vector force that points from the negative to the positive charge.
Formula for electric dipole moment?

What happens to an electirc dipole when placed in an external electric field?
The net force will be zero, and the field tends to align the dipole with exherts torque on the dipole.
