Question

A charge of +3 micro-coulombs is placed at the bottom left corner of a rectangle, a charge of -3 micro-coulombs is placed at the top left corner of a rectangle, a charge of +7 micro-coulombs is placed at the bottom right corner of a rectangle, and a charge of +7 micro-coulombs is placed at the top right corner of a rectangle. The rectangle has a height of 9.6 cm and a width of 15.4 cm. (See sketch). What is the magnitude of the total electric field at the middle of the left side of the rectangle in units of x 10⁶ N/C?
