Suppose four charges form a square of side d = 0.0161m. The value of each charge is q = 1.41x10^-6 C. Find the strength electric field halfway between two adjacent charges.

What are the magnitude and direction of an electric field that exerts a 1.45 x 10^-5 N upward force on a -2.60 uC charge?

Calculate the strength and direction of the electric field, E, due to point charge of 2.7 nC at a distance 5.6 mm from the charge. For the direction, consider the line joining the point charge and point at the distance 2.4mm. The direction on this line away from the charge is positive and the direction towards the charge is negative. What force does the electric field found in the previous example exert on a point charge of −2.3·10^-8 C?
