Physics - Magnetism Question with Solution | TestHub

A horizontal rod of mass $0.01\mathrm{kg}$ and length 10 $\mathrm{cm}$ is placed on a frictionless plane inclined at an angle $60^{\circ }$ with the horizontal and with the length of rod parallel to the edge of the inclined plane. A uniform magnetic field is applied 'Vertically downwards. If the current through the rod is $1.73\mathrm{A}$, then the value of magnetic field induction $B$ for which the rod remains stationary on the inclined plane is
