Physics - Magnetism Question with Solution | TestHub

A small particle of mass$1 \mathrm{kg}$and charge$1 \mathrm{C}$enters perpendicularly in a triangular region of a uniform magnetic field of strength$2\mathrm{T}$as shown in the figure. What is the maximum velocity (in$\mathrm{m} {\mathrm{s}}^{-1}$) of the particle with which it can enter so that it completes a half-circle in the region of the magnetic field?
