(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A point charge Q = 16.5uC is at the origin. Find the electric field vector at the point P with coordinates x = 15cm, y = 25cm, z = 0.

2. Relevant equations

E = kQ/d^2

F = QE

3. The attempt at a solution

Ok, so first to calculate the distance between the origin and point P I used the Pythagorean theorem, which comes out to be 29.15cm, or .2915m

Then I applied the formula above

[(9 x 10^9) (16 x 10^-6)] / [(.15)^2 + (.25)^2] which is equal to --->>> 1694117.647 N/C

so my question is

in order to get the electric field do I just multiply

(1694117.647) (16 x 10^-6) --->>> 27.11

it just doesn't seem right...

thanks
