Question

Radiation and Mangetism emissions arly researchers found that an electric or magnetic field could split radioactive nto three types of beams as illustrated below. Pb container Screen coated with ZnS *B Compound containing U or Th Magnet Which of the following statements accurately describes these characteristic radioactive decay products? Particle c represents a positron because it experiences the most deflection from passing through the magnetic field. All particles will have the same deflection if a stronger magnet is used. Particle represents a neutron since there is no deflection in its path due to its larger B mass. Particle A represents an alpha particle because of the upward and smaller deflection than that of particle C. Submit Answer Tries 0/1 selector takes advantage of region of crossed fields to allow any particles regardless of mass or charge with the right velocity to pass through undeflected. Inside the device there are a pair of plates creating an electric field and a magnetic coil creating

Explanation / Answer

(1) For radioactive emmision,

1st and 3rd option are correct.

1st: This is correct because the deflection shows that the particle has +ve charge which got deflected due to the magnetic field directed from North to south pole

3rd: There is no deflection in the particle and direction of magnetic field is also not along the motion hence particle must be neutral
