Explanation / Answer

Here ,

q = 6 * 10^-9 C

x1 = 0.150 m

x2 = - 0.150 m

part A)

for the electric field

Ex = k * Q/x^2 - k * Q/x^2

Ex = 0 N/C

part b)

Ey = 0 N/C

part C)

E = sqrt(Ex^2 + Ey^2)

E = 0 N/C

part D)

at the point x = 0.300 m

electric field , Ex = 9 *10^9 * 6 *10^-9 * (1/0.150^2 + 1/(0.150 + 0.30)^2)

Ex = 2667 N/C

part E)

as the charges are on x axis

Ey = 0 N/C
