Three positive point charges lie along a line as shown in the figure below. The charges \( q_{1} \) and \( q_{2} \) are separated by \( 2.0 \mathrm{~m} \) and are \( 15 \mu \mathrm{C} \) and \( 6 \mu \mathrm{C} \) respectively, while \( q_{3} \) is between them. If there is no net force on \( q_{3} \), how far is it situated from \( q_{1} ? \)
