Physics - Magnetism Question with Solution | TestHub

A conductor of length $\ell =10\mathrm{cm}$ is placed in E-W direction in a plane. Earth's horizontal magnetic field is $\mathrm{B}=$ 3 Tesla. Find the amount of charge (in mC) which passes through it when it is found to jump to height 5 cm. Mass of rod is 2 gm and $\mathrm{g}=10\mathrm{m}/{\mathrm{s}}^2$.
