Answer to Question #303598 in Field Theory for pianna

Question #303598

Calculate the magnitude and direction of the electric field 0.45 m from a +7.85 x 10–9 C point charge.

Expert's answer

Answer

Electric field is given by

"E=\\frac{KQ}{r^2}\\\\=\\frac{9*10^9**7.85*10^{-9}}{(0.45)^2}\\\\=348.89N\/m"
