Energia Potencial Elétrica e Potencial Elétrico

1 - (FEI) – In a vacuum, what is the electric potential generated by a point charge Q = 50 microC at a distance of 5.0 m from the charge? 2 - A positive point electric charge with a value of Q generates an electric field around itself. We assign an electric potential value V to each of these points. 3 - (UFPE) – The graph shows the dependence of the electric potential created by a point electric charge Q in a vacuum on the distance from the charge. Given the electrostatic constant k0 = 9.0 . 109 SI units, we can state that the value of the electric charge Q is:
