Two point charges, q1 (on the left) and q2 (on the right), are placed exactly 1.00 m apart. If q1 is 1.64 C and q2 is 4.88 C, at what distance from q1 (between the charges) will the net electric field be exactly zero? Give your answer in meters. (1.00 C = 1.00106 C) (Hint: rearrange the sum of the fields into quadratic form, and remember to include direction (+ or -) where appropriate in your sum of fields.)
