A particle moving in one dimension with constant acceleration takes 2secs to cover a distance of 80m between two points in 75 path it’s speed as 7 passes the second point is 20ms-1 calculate (a) the acceleration (b) the speed of the particle as it passes the first point

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.
