Problem 10-31(a) Vector electric field - Part 3

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 System C .


Correct!

This simplifies the problem so that one force only has one component.

Now add the forces to the drawing. Which is correct?

Four possible coordinate systems; A, B, C, D.

(A)

(B)

(C)

(D)
