A positive charge Q1 = 49.5 nC is located at the origin. A negative charge Q2 = -9.5 nC is located on the positive x-axis p = 7 cm from the origin. Calculate the location, x, on the x-axis, in centimeters, where the electric field is equal to zero.

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.

If anyone who can me with this hw? i would really appreciate it
