Answer:
a
Explanation:
When the particle is released from rest, it starts to move along the fields due to application of electric field.
The magnetic force acting on a moving charged particle is given by
F
=q(
v
×
B
)
Since velocity and magnetic fields are parallel, no magnetic force acts on the particle, hence it continues to move in a straight line along with constant acceleration.
