Question

Mark out the correct statement(s)

Answer 1

Correct option is D. In gamma decay, the energy released is in the form of energy carried by photons termed as gamma rays
For (a) as the mass of alpha particle is less than that of daughter nucleus the speed of alpha particle will be more to conserve momentum and thus more kinetic energy.

For (b) In beta decay, the change in binding energy appears as the mass-energy and kinetic energy of the beta particle, the energy of the neutrino, and the kinetic energy of the recoiling daughter nucleus.

For (c) the energy released in beta minus decay is shared between electron and antineutrino as the kinetic energy

For (d) the energy released is in the form of gamma radiation
