my school, i doubt the answer is correct or maybe the question is wrong...
the questions says the force when it moves in the direction of field...
answer is 0 because no force when in the direction of field i.e parallel
F=qVBsin•
where sin • is=0
thus
F=qVB*0 =F=0
but when force is perpendicular maximum force is obtained.

sin• =90= 1
F=qVB*1
F=qVB

there for the answer to the question above should have being 0
