Answer 2

Solution no.3)

Current in wire A,i1=8A

Current in wire B,i2=5A

Force exerted on 10cm section of wire A,

B=μ•2i1i21 / 4πr =2×10 to the power -5 T

Attractive force normal to A towards B, because current direction same.

Solution no.4)

Charge,q=1.6×10^-190C

Magnetic field B= 1 N/m

Angle theeta =30°

Velocity V =5×10^7 ms^-1

F=q(vector v × vector B)

=qvB sin theeta

=5×10^7×1.6×10^-19×1×sin 30 °

=8×10^-12×1/2

=4×10^-12N
