Question

Calculate the magnitude of the electric field at one corner of a square 2.12 m on a side if the other three corners are occupied by 4.75×10−6 C charges.

 

What is the direction of the electric field at the corner?

What is the direction of the electric field at the corner?

	along the side of the square between the corner and one of the charges toward the charge
	along the side of the square between the corner and one of the charges outward of the charge
	along the line between the corner and the center of the square toward the center
	along the line between the corner and the center of the square outward of the center
