A point charge $$2 \times 10^{-2}$$ C is moved from $$P$$ to $$S$$ in a uniform electric field of $$30$$ N C$$^{-1}$$ directed along positive $$x$$-axis. If coordinates of $$P$$ and $$S$$ are $$(1, 2, 0)$$ m and $$(0, 0, 0)$$ m respectively, the work done by electric field will be

A

$$1200$$ mJ

B

$$600$$ mJ

C

$$-600$$ mJ

D

$$-1200$$ mJ
