Electric Field - Three Charges I
Three charges, q1 = +3.96nC, q2 = -1.27nC, and q3 = +9.27nC, are at the corners of an equilateral triangle, each of whose sides are of length, L, as shown in the figure below.
The angle α is 60.0° and L = 0.437 m. We are interested in the unmarked point midway between the charges q1 and q2 on the x axis.
For starters, calculate the magnitude and direction of the electric field due only to charge q1 at this point.
Down Up Left Right
Calculate the magnitude and direction of the electric field due only to charge q2 at this point.
Down Up Left Right
Calculate the magnitude and direction of the electric field due only to charge q3 at this point.
Down Up Left Right
Now calculate the magnitude of the electric field from all three charges at a point midway between the two charges on the x axis.
Calculate the angle of the electric field relative to the positive (to the right) x-axis, with positive values up (counterclockwise) and negative down (clockwise). (enter the answer with units of deg)
If a tiny particle with a charge q= 1.18nC were placed at this point midway between q1 and q2, what is the magnitude of the force it would feel?
