Compute the electric field at a point .033 cm from q2 along a line running toward q3 in the figure below(adsbygoogle = window.adsbygoogle || []).push({});

square with charges -10uC on top left and top right and on the bottom +5uC on both left and right. q1 top left q2 top right q3 bottom right q4 bottom left I need the magnitude __N/C each side of the square is .1 m by the way

2. Relevant equations

kq/r^2

3. The attempt at a solution

6.71641791x10^5-q4 to test charge

3.10580441x10^6-q3 to test charge

8.26446281x10^7-q2 to test charge

8.11615113x10^6-q1 to test charge

angle facing test charge on top triangle- 18.2629 degrees

angle facing test charge on bottom triangle- 33.8221 degrees

my friend told me to do this form here to get the answer but i am so confused

"ok now break down the fields into x and y components based on those angles. the x and y for the 2 triangles. Basically the 2 sides find the field on those 2 sides

using the field u found and the angle and sin and cos. Then u take the x and y each triangle and add them up --- x+x and y+y. then add the other 2 fields u got the the the y total. Now take the x total and the new y total and pythagorize that and that is the answer.
