Problem 10-31(a) Vector electric field - Part 8 - A

Diagram indicating the  positions of two particles.

The figure shows the positions of two a particles (charge on each is +2e) and an electron. What are the magnitude and direction of
(a) the resultant force on the electron?
(Hint: choose the +x axis along the line from the electron to the right-hand a particle.)

[Ans.(a) 1.31×108N at 13.3 to left of line from electron to right-hand a]

No. These are vector components so you must use the Pythagorean theorem.
