A long solenoid carrying a current 
is placed with its axis vertical as shown in the figure. A particle of mass 
and charge 
is released from the top of the solenoid. Its acceleration is ( 
being acceleration due to gravity)
A
greater than 
B
less than 
C
equal to 
D
None of these
Text Solution
Verified by ExpertsThe correct answer is:
C
As magnetic field and velocity of charge is in same direction, so magnetic force on it is zero. Hence, it falls with acceleration equal to 
.
