A point mass is placed inside a thin spherical shell of radius R and Mass M at a distance R/2 from the Centre of the shell. The gravitational force exerted by the shell on the point mass is​

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.
