Four identical charged particles (q = +10.9 µC) are located on the corners of a rectangle as shown in the figure below. The dimensions of the rectangle are L = 56.4 cm and W = 14.9 cm.
(a) Calculate the electric field at the lower left corner due only to the two charges on the far right side of the rectangle. E with arrowtwo charges on right only = ( N/C)i hat + ( N/C)j hat
(b) Calculate the electric field at the lower left corner due to all three charges not at that location. E with arrowat lower left = ( N/C)i hat + ( N/C)j hat
(c) Calculate the magnitude of the total electric force exerted on the charge at the lower left corner by the other three charges. N (d) Calculate the direction of the total electric force exerted on the charge at the lower left corner by the other three charges. ° (counterclockwise from the +x-axis)
