A charge $$Q_2 = 8.854 \times 10^{-9} C$$ is located in a vacuum at $$P_2 (2,3,1)$$. The force on $$Q_2$$ due to a charge $$ Q_1 = 4 \pi \times 10^{-3} C$$ at $$P_1 (2,2,1)$$ is: (Note: All the coordinates are measured in Meters. $$a_x, a_y$$, and $$a_z$$ are unit vectors in X, Y and Z direction respectively.)

A

$$ a_y N $$

B

$$ -a_y N $$

C

$$ 4a_x + 5a_y + 2a_z N $$

D

$$ -4a_x - 5a_y - 2a_z N $$
