Answer:
V = 32.2 10³ V
Explanation:
The electric potential is a scalar quantity given by the expression
V = h ∑ [tex]\frac{ q_i}{r_i}[/tex]
Let's find the distance from each corner to the center of the square, using Pythagoras' theorem
r = [tex]\frac{1}{2} \sqrt{a^2 + b^2}[/tex]
indicate that all charges have the same magnitude and the casticista from each scheme to the center is r
V = k q ([tex]\frac{4}{r}[/tex])
let's calculate
r = ½ [tex]\sqrt{2^2 + 4^2}[/tex]Ra 2² + 4²
r = 2,236 m
V = 9 10⁹ 2 10⁻⁶ 4 / 2,236
V = 32.2 10³ V
