Electric Fields
Three point charges of strengths and are fixed in a right triangle as shown above.
The distance between and is and the distance between and is What is the approximate electric field strength at location of charge due to the other two charges?
Four point charges, each equal to are held at the corners of square of side length on the -plane. Find the magnitude and sign of a charge placed at the center of the square such that the system of charges is in equilibrium.
Three point charges, each equal to are held at the corners of equilateral triangle of side length on the -plane. Find the magnitude and sign of a charge placed at the center of the triangle such that the system of charges is in equilibrium.
Two charges, each equal to are held a certain distance apart. A charge is placed exactly midway between them. Find the magnitude and sign of such that the system of the three charges is in equilibrium.
Two points charges and are held on the -axis. The point charge is at and is at the origin. Where on the -axis should a third charge be placed so that charge does not experience any net force?
