A particle of specific charge 
is projected from the origin towards positive X-axis with a velocity of 
in a uniform magnetic field 
. The velocity v of the particle after time 
will be
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Motion of charged particle in magnetic field ( 
) is shown below
Time period, 
Since, the particle will be at point P after time,
Hence, if it is deviated by angle θ, then 
.
Therefore, velocity of the particle after 
, is given by
