Four identical charged particles (g = +10.2 µC) are located on the corners of a rectangle as shown in the figure below. The dimensions of the rectangle are L = 65.4 cm and W = 15.1 cm. W L b. (a) Calculate the magnitude of the total electric force exerted on the charge at the lower left corner by the other three charges. 44 Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. N
