Lesson 2: Electric field due to multiple charges - Superposition!

# Find where a third charge would be in equilibrium

Let's solve a numerical and see how to figure out where the null point is. The null point is where the net electric fields due to all charges add up to be zero. Created by Mahesh Shenoy.

• Well, I guess you wanna assume an electric dipole and wanna know where the equilibrium point will lie (the electric field will be zero) ?

Well, it has an amazing result. But a simple answer would be, if you assume an electric dipole there doesn't exist any finite distance where you can get zero electric field. For an electric dipole the electric field will be zero at infinity.
