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) \(F_1\) \(-F_2 \cos 53.1\)
