Explanation / Answer

a)
F = B*I*L*sin thetha
thetha is angle between B and I

b)
F = B*I*L*sin thetha
= 0.55*1.2*0.55*sin 90
= 0.363 N

c)
B is up
I is inward
direction of F = direction of IXB
=RIGHT
answer: right

d)
FB= 0.363 N

parallel component = FB*cos 12
= 0.363*cos 12
=0.355 N

Answer: 0.355 N
