Problem 4: In the figure, the point charges are located at the corners of an equilateral triangle 29 cm on a side.
Part (a) Find the magnitude of the electric field, in newtons per coulomb, at the center of the triangular configuration of charges, given that q_a = 2.9 nC, q_b = -6.1 nC, and q_c = 11 nC. Numeric A numeric value is expected and not an expression.
Part (h) Find the direction of the electric field in degrees below the right-pointing horizontal (the positive X-axis). Numeric A numeric value is expected and not an expression.
