 The superposition principle states that:
 > The net force acting on a point charge is equal to the sum of all individual forces.
 
-This means that to find the net force acting on a single charge, you add up all of the individual forces acting on that charge.

+# The Electric Dipole
+An electric dipole consists of two point charges of equal magnitude but opposite sign. Many molecules behave like dipoles.
+- **Electric dipole moment** ($p$) is defined as the product of the charge $q$ and the separation $d$ between the two charges making up the dipole. $p = qd$
