# Did you get that

Four point charges $$q_1$$, $$q_2$$, $$q_3$$ and $$q_4$$ with charges $$\text{1C, 2C, 3C, 4C}$$ are placed at coordinates (0,0,0) , (1,0,0), (0,1,0) and (0,0,1) respectively.

Assuming one unit equal to one meter, find $$\sum \vec{F_{i}}$$ , where $$\vec{F_{i}}$$ represents force on one due to rest three.
