A proton of mass 
and charge 
is projected with a speed of 
at an angle of 
to the X - axis. If a uniform magnetic field of 0.104 Tesla is applied along 
axis, the path of proton is
A
A circle of radius = 0.2 m and time period 
B
A circle of radius = 0.1 m and time period 
C
A helix of radius = 0.1 m and time period 
D
A helix of radius = 0.2 m and time period 
Text Solution
Verified by ExpertsThe correct answer is:
C
As, velocity 
component is along magnetic field 
.
So, path is helical. Radius of a helix,
Time period,
