# Problem 10-31(a) Vector electric field - Part 2 - B

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) $1.31 \times 10^{-8} N$ at $13.3^\circ$ to left of line from electron to right-hand a]

Accumulated Solution

Correct!

What are the $x$-components of $F_1$ and $F_2$?

Solution $F_1$ $F_2$
(A) $F_1$ $F_2 \sin 53.1$
(B) $F_1$ $F_2 \cos 53.1$
(C) $F_1$ $-F_2 \sin 53.1$
(D) $F_1$ $-F_2 \cos 53.1$
