3.24 Force between two short charged segments. Two charged lines are colinear as shown in Figure 3.43. The total charge on line 1 is Q₁ [C]; the total charge on line 2 is Q2 [C]. On each line the charge is uniformly distributed over the length of the line. Given the lengths of the lines (L1 [m] and L2 [m]) and the distance between them as a [m], calculate the force one line exerts on the other if both are in free space. Figure 3.43 L2 Q2 L₁ a
