Here ,
q1 = -3.8 nC
q2 = 3.8 nC
for the electric field due to q1 is E1
E1 = k * q1/y^2 (-j)
E1 = 9*10^9 * 3.8 *10^-9/.64^2 j
E1 = 83.5 j
NOw , for electric field due to q2
theta = arctan(0.65/1.5)
theta = 23.4 degree
for the electric field due to q2
E2 = 9*10^9 * 3.8 *10^-9/(1.5^2 + 0.65^2) * (- cos(23.4) i - j * sin(23.4))
E2 = -11.74 i - 5.08 j
as Enet = E1 + E2
Now , for
Ex = -11.74 N/C
Ey = 83.5 - 5.08
Ey = 78.4 N/C
