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

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

Accumulated Solution

Coordinate diagram B Coordinate System C .

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)	$F_1$	$-F_2 \cos 53.1$
