Q1

A 10 cm long wire lies along y-axis. It carries a current of 1.0 A in positive y-direction. A magnetic field \(\vec{B}=(5\mathrm{mT})\overset{^}{j}-(8\mathrm{mT})\overset{^}{k}\) exists in the region. The force on the wire is :

a

\((0.8\mathrm{mN})\overset{^}{\mathrm{i}}\)

b

\(-(0.8\mathrm{mN})\overset{^}{\mathrm{i}}\)

c

\((80\mathrm{mN})\overset{^}{\mathrm{i}}\)

d

\(-(80\mathrm{mN})\overset{^}{\mathrm{i}}\)
