Problem 10-31(a) Vector electric field - Part 5 - 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 .

\(F_{1x} = F_1, F_{2x} = F_2 \cos 53.1\)


No. 

Diagram of F

What is the \(y\) component of \(F\)?

\(F_y = F \sin \theta\)

\(F_y = F \cos \theta\)
