Question
In the figure, the point charges are located at the corners of an equilateral triangle 21 cm on a side.
a) Find the magnitude of the electric field, in newtons per coulomb, at the center of the triangular configuration of charges, given that qa = 1.5 nC, qb = -9.4 nC, and qc = 1.9 nC.
b) Find the direction of the electric field in degrees below the right-pointing horizontal (the positive x-axis).
Expert Solution
Step 1
a)
Let d be distance between the charges and the center of the equilateral triangle and L be the side length.
