An electron experiences a force (1 · 6 × 10^-16 N ) i in an electric field E. The electric field E is:
An electron experiences a force $\displaystyle \left(1 \cdot 6 \times 10^{-16} \mathrm{~N}\right) \hat{\mathrm{i}}$ in an electric field $\displaystyle \overrightarrow{\mathrm{E}}$. The electric field $\displaystyle \overrightarrow{\mathrm{E}}$ is :
Official answer
(B)
$\displaystyle -\left(1.0 \times 10^{3} \frac{\mathrm{~N}}{\mathrm{C}}\right) \hat{\mathrm{i}}$
