7. Three positive charges, q1, q2, and q3 are connected with two strings of equal length L. Due to mutual Coulomb repulsion the charges spread out and form a straight line such that the distance between 1 and 3 is 2L and, with 2 in the middle, the distance between 1 and 2 or 2 and 3 is just L. Find the tension force in each string.
