A circular coil 16.0 cm in d5+hbjl5yfk4*1b m4 fpk hmni .iameter and containing)h/r.spxdq4mc .w-ng mxs- x4 nine loops lies flat on the ground. The Earth’s magnetic field at this location has maspgxrqc-xx/.n)-4.4wm sd h mgnitude $5.50\times10^{-5}\mathrm{~Т}$ and points into the Earth at an angle of 56.0$^{\circ}\,$ below a line pointing due north. If a 7.20-A clockwise current passes through the coil,
(a) determine the torque on the coil, $\times10^{-5}\mathrm{m}•\mathrm{N}$
