(a)

To determine

To sketch: The four possible force diagram represent the forces ${\overrightarrow{F}}_1$ and ${\overrightarrow{F}}_2$ of the charge $q_1$ and $q_2$ exerts on the charge $q_3$.

(b)

To determine

The sign of charge $q_1$ and $q_2$ exerts on $q_3$.

(c)

To determine

The magnitude of charge $q_2$ exerts on charge $q_3$.

(d)

To determine

The magnitude of net force on charge $q_3$.
