Positive charge q, with a value of 4.00 nc, is distributed uniformly along the x-axis from x = 0 to x = a where a is 3.8 cm. a positive point charge q, with a value of 7.2 nc is located on the positive x-axis at x = a r, where r is 3.1 cm. calculate the x and y components of the electric field produced by the charge distribution q at points on the positive x-axis where x > a. ex = ey = calculate the magnitude of the force that the charge distribution exerts on q.
