The answer is 0.18 to the left.

I calculated the magnitude and got 0.18 by:

finding F_12 and F_13, which is .144 N and .036 N, respectively.

F_1 = F_12 + F_13 = .18 N,

where 1 is charge at origin, 2 is charge at .5 m, and 3 is charge at 1m.

Is this even correct at all? Why must F_12 and F_13 be added?

How is the direction to the left?

Thanks.
