Question

1. An electrons placed uniform electricfield directed along negative X axis. in which direction will it tend to move​

Answer 1

Answer:

The velocity of electron

v

is along (+x) axis. The

E

field applies a force along (−y) axis . In order to have ∑

F

=0 on the electrons

B

field must apply force in +y) axis

As Lorintz force expersion

F

m

=l(

V

×

B

).

F

m

along (+y)

thus we get

B

should be along (−z) axis
