field of + 2uC
here
r2 = 22 + 22 = 8
x - component = 9e9 * 2e-6 * cos 45 / 8 = 1590.99 N/C
y - component = - 9e9 * 2e-6 * sin 45 / 8 = - 1590.99 N/C
--------------------
field of - 2 uC
x - component = 9e9 * 2e-6 * cos 45 / 8 = 1590.99 N/C
y - component = - 9e9 * 2e-6 * sin 45 / 8 = 1590.99 N/C
so,
we can see that y - component cancels out
we have only x components which will add up
so,
resultant = y - component = 0
resultant = x - component = 3181.98 N/C
so,
magnitude = 3181.98 N/C

2 3 4 ds Electric Field 2. Just like in question 1, a charged particle with charge qs 20 nC is placed at the origin. This is the "source particle". The charge on the source particle creates an electric field at every point in space around the particle. a. Use your answer in question la and the equation FE to determine the electric field vector (E) at position 1. Draw the electric field vector with its tail at position 1....
