11. A straight segment of wire is placed in a uniform
magnetic field. The current in the wire is 5.0 A, and
it is horizontal to the ground, pointing 35° North of
West. The magnetic field is 0.7 T and is vertica!,
pointing directly down into the ground. What is
the magnitude and direction of the magnetic force
per length on the wire?
A 0.0 N/m
B 3.50 N/m, 35° West of South
C 2.01 N/m, 35° West of South
D 2.01 N/m, 35° East of North
E 3.50 N/m, 35° East of North
