A Rigid Rectangular Loop, Measuring $0.30 \mathrm {~m}$ By $0.40 \mathrm {~m}$

Multiple Choice

A rigid rectangular loop, measuring $0.30 \mathrm {~m}$ by $0.40 \mathrm {~m}$ , carries a current of $9.9 \mathrm {~A}$ , as shown in the figure. $\mathrm { A }$ uniform external magnetic field of magnitude $1.8 \mathrm {~T}$ in the $- x$ direction is present. Segment CD is in the $x z$ -plane and forms a $19 ^ { \circ }$ angle with the $z$ -axis, as shown. What is the $y$ component of the magnetic force on segment $A B$ of the loop?

A) $0.0 \mathrm {~N}$
B) $- 1.7 \mathrm {~N}$
C) $+ 5.1 \mathrm {~N}$
D) $+ 1.7 \mathrm {~N}$
E) $- 5.1 \mathrm {~N}$
