Physics - Magnetism Question with Solution | TestHub

Four particles$\mathrm{A}, \mathrm{B}, \mathrm{C}$and$\mathrm{D}$of masses${\mathrm{m}}_{\mathrm{A}},{\mathrm{m}}_{\mathrm{B}},{\mathrm{m}}_{\mathrm{C}}$and${\mathrm{m}}_{\mathrm{D}}$respectively, follow the paths shown in the figure, in a uniform magnetic field. Each particle moving with same speed.${\mathrm{Q}}_{\mathrm{A}},{\mathrm{Q}}_{\mathrm{B}},{\mathrm{Q}}_{\mathrm{C}}$and${\mathrm{Q}}_{\mathrm{D}}$are the specific charge of particles$\mathrm{A}, \mathrm{B}, \mathrm{C}$and$\mathrm{D}$respectively (assume that the motion of each particle is in the same plane perpendicular to the magnetic field).
