Hint: In electric or magnetic fields, only charged particles are deflected. Gamma rays are high-energy electromagnetic waves, while alpha and beta rays have net charges. Positively charged alpha particles, negatively charged beta particles, and electrically neutral gamma radiation This

Complete answer:
1.When a charged particle moves through an electric or magnetic field, it is deflected by the field.
2.Because they have two protons and two neutrons, alpha particles are positively charged. While neutrons have no charge, protons have a net positive charge, and alpha particles have a positive charge as a result.
3.Helium nuclei are another name for alpha particles. Negatively charged beta particles have one unit of negative charge.
4.Beta particles are electrons that are emitted as a result of radioactive processes. Gamma radiation has no electrical charge.
5.Gamma rays are electromagnetic waves with a high energy but no net electrical charge. This means that electric fields can deflect alpha and beta radiation but not gamma radiation.
6.As a result, gamma rays are waves that cannot be deflected by an electric or magnetic field.

Note:
While the electric field can act on both static and moving charges, the magnetic field can only act on charges that are moving with a non-zero velocity in it. In a magnetic field, stationary alpha and beta particles will not experience any force. The Lorentz formula is used to calculate the magnitude of this force, which is dependent on the orientation of the electric and magnetic fields.
