Question
Physics Question on Moving charges and magnetism
A charge 'q' moves in a region where electric field and magnetic field both exist, then force on it is
A
q ( V × B)
B
q E + q ( V × B)
C
q E + q ( B × V )
D
q B + q ( E × V )
Answer
q E + q ( V × B)
Explanation
Solution
The correct option is (B) : q E + q ( V × B)
Lorentz forece FL = Fe + Fm = q E + q( v × B)
