Question
A very long straight wire carries a current 
. At the instant when a charge 
at point 
has velocity 
, as shown, the force on the charge is
- Opposite to OX
- Along OX
- Opposite to OY
- Along OY
The correct answer is: Along OY
Magnetic field produced by wire at the location of charge is perpendicular to the paper inwards. Hence by applying Fleming's left hand rule, force is directed along OY.
