9. Using the diagram shown below: (a)Calculate the electrostatic force exerted by \( \mathrm{Q}_{1} \) on \( \mathrm{Q}_{2} \) (b) By proportional reasoning, determine the electrostatic force exerted by Q3 on \( \mathrm{Q}_{2} \) (c) Use a vector diagram to determine the resultant electrostatic force on Q2 (d) Determine the resultant electric field due to \( Q_{1} \) and \( Q_{3} \) at the point occupied by \( \mathrm{Q}_{2} \)
