Answer:
D)A positive charge sent along the axis of a solenoid
Explanation:
Two parallel wires carrying currents in same direction attract each other.
Two parallel wires carrying currents in opposite direction repel each other.
A positive charge is projected between the pole pieces of bar magnet feels a force = q( V *B)
) which is non zero since angle between V and B is non-zero.
A positive charge projected along the axis of a solenoid carrying current feels no force because in solenoid B is along the axis so
V*B
is zero.
