B. 1.5 * 10^4 N/C , opposite
C. 3.0 * 10^4 N/C , opposite
D. 3.0 * 10^4 N/C , same

michele_laino · Answer

here we have to apply this formula:
$$\Large F = QE$$
or:
$$\Large  E = \frac{F}{Q} = \frac{{6 \times {{10}^{ - 2}}}}{{2 \times {{10}^{ - 6}}}}$$

furthermore, since Q is positive, then vectors F and E have the same orientation
