Physics - Magnetism Question with Solution | TestHub

A long straight wire carries a certain current and produces a magnetic field $2\times 10^{-4}\frac{\text{ Weber }}{{\mathrm{m}}^2}$ at a perpendicular distance of $5\mathrm{cm}$ from the wire. An electron situated at $5\mathrm{cm}$ from the wire moves with a velocity $10^7\mathrm{m}/\mathrm{s}$ towards the wire along perpendicular to it. The force experienced by the electron will be (change on electron $1.6\times 10^{-19}\mathrm{C}$ )NEET 2013 (Karnataka)
