Question

20. A long solenoid carrying a current I is placed with its
axis vertical as shown in the figure. A particle of
mass m and charge q is released from the top of the
solenoid. Its acceleration is (g being acceleration due
to gravity)
m, qe
(a) greater than g
(c) equal to g
(b) less than g
(d) None of these​

Answer 1

less than g

Explanation:

due to the charge moves through long solenoid it creates a magnetic field around it thus it falls slower
