In a rectangular coordinate system, a positive point charge q = 4.00 nC is placed at the point x = 0.220 m, y = 0, and an identical point charge is placed at x = -0.220 m, y = 0. Find the x and y components and the magnitude and direction of the electric field at the following points. Find the x and y components and the magnitude and direction of the electric field at x = 0.220 m, y = -0.350 m.

Solution

E₁ =kQ₁/r² + kQ₂/r²

E₁ =(9 * 10⁹) * (4 * 10 ^-9 ) / 0.220²

= 743.801 N/C

E₂= (9 * 10⁹) * (4* 10^-9) / .22²

⁼ 743.801 N/C

total E = 1487.603 N/C
