Do not store equations in your calculator. You need to show all of your work for full credit. ________________________________________________________________________________ In the figure below right, two particles are fixed to an x axis. Particle 1 of charge q 1 = +2.00 μ C is located at the origin and particle 2 of charge q 2 = -6.00 μ C is located a distance L = 3.00 m to the right of the origin. a) We subdivide x axis into three regions: the region to the left of q 1 (Region 1), the region between q 1 and q 2 (Region 2) and the region to the right of q 2 (Region 3). Draw the electric field vector due to q 1 and that due to q 2 at a point in each region. If there is a point where the net electric field is zero, in which region the point must be? In region 2, the electric fields due to q
