An electron moving with a velocity v $=(5\mathrm{.}0107)$i m$/$s $$enters a region of space where perpendicular electric and magnetic fields are present. The electric field is$$ E$=-104$ j$.$ What magnetic field will allow the electron to go through the region without being deflected?

Group of answer choices

B $=(+2\mathrm{.}010-4$ T$)$ j

B $=(+2\mathrm{.}010-4$ T$)$k

B $=(-2\mathrm{.}010-4$ T$)$ j

B $=(+5\mathrm{.}010-4$ T$)$ k$$

B $=(-2\mathrm{.}010-4$ T$)$ k
