Question

Calculate the magnitude of the electric field at one comer of a square 182 m on a side if the other three comers are occupied by 1 25 times 10^-6 C charges Express your answer to three significant figures and include the appropriate units. What is the direction of the electric field at the corner? along the side of the square between the come, and one of the charges outward of the charge along the side of the square between the corner and one of the charges toward the charge along the line between the corner, and the center the square outward of the center along the line between the corner, and the center of the square toward the center

Explanation / Answer

a] E = summation of kq/r^2

= [sqrt 2] *[9e9*1.25e-6/1.82^2] + 9e9*1.25e-6/[2*1.82^2]

= 6501 N/C answer

b] third statement is correct
