Physics - Electrostatics Question with Solution | TestHub

A proton of mass $1.67\times 10^{-27}\mathrm{kg}$ enters a uniform magnetic field $1\mathrm{T}$ of at point $\mathrm{A}$ shown in figure with a speed of $10^7{\mathrm{ms}}^{-1}$.
The magnetic field is directed normal to the plane of paper downwards. The proton emerges out of the magnetic field at point $C$, then the distance $\mathrm{AC}$ and the value of angle $\theta$ will respectively be
