Positive charge q is distributed uniformly along the x-axis from x=0 to x=a. a positive point charge q is located on the positive x-axis at x=a+r, a distance r to the right of the end of q. (figure 1) calculate the x-component of the electric field produced by the charge distribution q at points on the positive x-axis where x> a. express your answer in terms some or all of the variables q, a, x, r, and constant k. calculate the y-component of the electric field produced by the charge distribution q at points on the positive x-axis where x> a. express your answer in terms some or all of the variables q, a, y, r, and constant k. calculate the magnitude of the force that the charge distribution q exerts on q. express your answer in terms some or all of the variables q, q, a, r, and constant k
