Electric Charges & Fields: Gauss's Law
What is the direction of the electric field due to a positive charge?
Two point charges are placed on the x-axis. A charge of +3q is at x = 0 and a charge of -q is at x = a. At what point on the x-axis is the net electric field zero?
What is the definition of an electric field?
A point charge of +2.0 is placed at the origin. What is the magnitude of the electric field at a point 3.0 m away?
