X-ray beam can be deflected:
✓
Answer
- Neither by an electric field nor by a magnetic field.
Since X-rays do not have any charged particles, they are not deflected by an electric field or a magnetic field.

An electron, a proton, a deuteron and an alpha particle, each having the same speed are in a region of constant magnetic field perpendicular to the direction of the velocities of the particles. The radius of the circular orbits of these particles are respectively $R_e, R_p, R_d$ and $R_\alpha$. It follows that
