Question

A point charge moving in a magnetic field of 1.21 Tesla experiences a force of 0.794E-11 N. The velocity of the charge is perpendicular to the magnetic field.

In this problem, we use the points of the compass and `into' and `out of' to indicate directions with respect to the page. If the magnetic field points south and the force points out of the page, then give ALL possible correct answers for the charge Q (i.e., B, AC, BCD...).

A) Q is negative, moving west
B) Q is negative, moving north
C) Q is negative, moving east
D) Q is positive, moving east
E) Q is positive, moving west

Explanation / Answer

apply the flemings right hand rule , you will get A and E as correct answers
