The radiationns from a naturally occuring radioactive substance as seen after deflection by a magnetic field in one direction are Only `alpha`-rays b. Only `beta`-rays c. Both `alpha`-and `beta-`rays d. Either `alpha`-or `beta`-raysA. a.Only `alpha`-raysB. b. Only `beta`-raysC. c. Both `alpha`-and `beta-`raysD. d. Either `alpha`-or `beta`-rays |
Answer» Correct Answer - d. Either `alpha`-or `beta`-rays Both `alpha`particles deflect in opposite direction in the presence of magnetic field. Here only one deflection is observed that will be for either `alpha`- or `beta-`rays. |
