A strip of invisible tape 0.12 m long by 0.014 m wide is charged uniformly with a total net charge of 3 nC (nano = 1e-9) and is suspended horizontally, so it lies along the x axis, with its center at the origin, as shown in the diagram.
Calculate the approximate electric field at location < 0, 0.03, 0 > m (location A) due to the strip of tape. Do this by dividing the strip into three equal sections, as shown in the diagram, and approximating each section as a point charge.
What is the approximate electric field at A due to piece #2?

Homework Equations

9e9*Charge*Vector Hat/(Vector Magnitude)^2

The Attempt at a Solution

okay so for tape #3 the Vector R is <0, 0.03, 0 > - <0.06, 0, 0> = <-.06, .03, 0>
That means magnitude is 0.0671
and that means Vector R Hat is <-.8942, .4471, 0>

plug this into 9e9*1e-9*<-0.8942, .4471, 0>/(0.0671)^2

and I get <1787.44, 893721, 0>

Which is wrong... why?

before anyone wastes their time, my R vector was wrong
