Multiple choice

The majority carriers in an n-type semiconductor have an average drift velocity v in a direction perpendicular to a uniform magnetic field B. the electric field E induced due to Hall effect acts in the direction

  1. v x B

  2. B x v

  3. along v

  4. opposite to v
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

According to Hall effect the direction of electric field is same as that of direction of force exerted. $$E = -v \times B \\ or \hspace{0.5cm} E = B \times v$$
