A wire $($Imass $=50g,$ length $=40cm,g=9\mathrm{.}8\frac{m}{s^2})$ is suspended horizontally by two vertical wires which conduct a current $I=10\mathrm{.}0A,$ as shown in the figure. The magnetic field in the region is into the paper and has a magnitude of $60mT.$ What is the tension in either wire?

Select one:

a$.341mN$

b$.365mN$

c$.485mN$

d$.425mN$
