Legal. This shows gamma rays are uncharged as they do not experience a force when passing through the lines of a magnetic field. So if Fleming's left-hand rule tells us positives are flowing in one direction and we know that in reality our charged things are flowing in the other direction then we know that our charged things must be negative. Please visit this website to see the detailed answer. \end{align}\]. Particles, such as protons and cathode rays, interact with the electromagnetic field in unique ways. Beta rays (light, negatively charged electrons) are deflected strongly in the opposite direction. An alpha particle consists of two neutrons and two protons bound together. (a) In what direction should the magnetic field be applied? What is the effect of magnetic field on gamma particles? Due to their high density and charge, Beta particles tend to be deflected in an electric field more. If this angle were \(0^o\), only parallel velocity would occur and the helix would not form, because there would be no circular motion in the perpendicular plane. The gamma ray has no charge so it is not affected by this 'electric landscape' and will just continue on its straight path. Please visit this website to see the detailed answer. In the second case, the centripetal force needed is much higher for the particle with larger mass, This force is caused by the interaction between charged particles and the electromagnetic field. Please visit this website to see the detailed answer. The force on the $\alpha^{++}$ particle is twice that on the $\beta^-$ particle, but also the velocity of the $\alpha^{++}$ is much smaller, so it's easier to change direction. If the probability that an alpha will deflect is $1/10000$, for $n$ layers, is the probability is only $1/10000n$? This is due to the fact that like charges repel each other.
