⚡ ELETROSTÁTICA - UEL - FORÇA ELÉTRICA 👨‍🏫

Hi everyone! In this video, I've provided a step-by-step guide to arrive at the requested result in a clearer way. I hope this helps you! (UEL - Electrostatics - Electric Force - Coulomb's Law): Four electric charges are fixed at the vertices of a square with side L, as shown in the figure, with the magnitudes and signs of the charges indicated. For the total electric force on one of the charges +q to be zero, the magnitude of the charge -Q must be equal to: a) q√2 d) ((q√2))/2 b) q e) ((q√2))/4 c) ((q))/2
