Three Point Charges Are Located on The $x$ -Axis the First Charge

Three point charges are located on the $x$ -axis. The first charge, $q_{1}=10.0 \mu C$ , is at $x=-1.00 \mathrm{~m}$ ; the second charge, $\mathrm{q}_{2}=20.0 \mu \mathrm{C}$ , is at the origin; and the third charge, $\mathrm{q}_{3}=-30.0 \mu \mathrm{C}$ , is located at $\mathrm{x}=2.00 \mathrm{~m}$ . Which charge is subjected to the force of greatest magnitude?

A) $\mathrm{q}_{1}$
B) $\mathrm{q}_{2}$ and $\mathrm{q}_{3}$ (equal)
C) $\mathrm{q}_{2}$
D) $\mathrm{q}_{1}$ and $\mathrm{q}_{2}$ (equal)
E) $\mathrm{q}_{3}$
