An 
‐particle is moving along a circle of radius 
with a constant angular velocity 
. Point A lies in the same plane at a distance 
from the centre. Point A records magnetic field produced by 
‐particle. If the minimum time interval between two successive times at which A records zero magnetic field is‘ 
. the angular speed 
, in terms of 
is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Point 
shall record zero magnetic field when the 
‐particle is at position 
and 
as shown in figure. The time taken by 
‐particle to go from 
to 
is
