Problem 10-38 Addition of Electric fields

Two negative charges have locations as shown in the Figure. Charge $q_1$ is  $-3.6\times 10^{-8} C;$ charge $q_2$ is  $-5.2 \times10^{-8} C.$ What is the electric field (magnitude and direction) at (a) $\text{point A}$? (b) $\text{point B}$?

The direction of the field $E_1$ due to $q_1$ at the $\text{point A}$ is:

(A)

(B)

(C)
