Integrate your expressions for dEx and dEy from θ=0 to θ=π. The results will be the x-component and y-component of the electric field at P .
Express your answers separated by a comma in terms of some, all, or none of the variables Q
and a and the constants k and π.

Why is it important always to use horizontal bars in unit fractions when performing unit conversions?

Along the line connecting the two charges, at what distance from the charge q1 is the total electric field from the two charges zero? express your answer in terms of some or all of the variables s, q1, q2 and k =14ï€ïµ0. if your answer is difficult to enter, consider simplifying it, as it can be made relatively simple with some work.
