Questions
An electron is moving along positive x-axis. To get it moving on an anticlockwise circular path in x-y plane, a magnetic field is applied
a
along positive y-axis
b
along positive z-axis
c
along negative y-axis
d
along negative z-axis
detailed solution
Correct option is B
For the particle to move along anticlockwise path, force should be along j^. Velocity is along i^Now F→m=-e(v→×B→)In terms of unit vectors only,∣j^=-(i^×?^) or j^=?^×i^ Clearly, ?^ is k^. .Talk to our academic expert!
