Week 1 Homework Assignment

1. Three positive particles of charges 11.0mC are located at the corners of an equilateral triangle of side 15.0cm. Calculate the magnitude and direction of the net force on each particle.
2. What is the magnitude and direction of the electric field at a point midway between a -8.0mC and a +6.0mC charge4.0cm apart?
3. Calculate the electric field at the center of a square 60cm on a side if one corner is occupied by a +45.0-mC charge and the other three are occupied by - 31.0-mC  charges.
