Homework Statement
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.
Homework Equations
E = kQ/d^2
F = QE
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
