Question
Three point charges are arranged at the corners of a square of side L as shown in the figure below. What is the potential at the fourth corner (point A), taking V = 0 at a great distance? Let q1 = -4Q and q2 = 3Q. (Use kfor Coulomb's constant.) I just need the equation
Explanation / Answer
potential at A = k * [ (Q / ( L * sqrt(2) ) + ( -4Q / L ) + ( 3Q / L ) ]
