Electric Field of Equilateral Triangle Charge Distribution

Click For Summary
SUMMARY

The discussion focuses on the electric field generated by three small, negatively charged spheres located at the vertices of an equilateral triangle. Participants analyze the electric field lines and forces acting on a test charge placed within the field. Key calculations include determining the distance between protons under a repulsive force, the net force on a third charge between two point charges, and the electric field strength at a specific point. The importance of correctly identifying the direction of forces and electric fields based on charge signs is emphasized throughout the conversation.

But you have to choose the vector carefully.

Force exerted on charge at B by charge at A is in the direction of AB, and electrostatic field intensity E at B due to charge at A is in the direction AB.

So, if the charge at A is actually negative, putting in the actual negative value gives you an intensity in the direction of -AB, as should be the case.
