Problem 10-31(a) Vector electric field - Part 8 - A
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) 1.31×10−8N at 13.3∘ to left of line from electron to right-hand a]
Accumulated Solution
F1x=F1,F2x=F2cos53.1F1y=0,F2y=F2sin53.1F1=1.045×10−8NF2=3.76210−9N
No. These are vector components so you must use the Pythagorean theorem.
