The energy spectrum of β - p a r t i c l e s [number N E as a function of β - energy E ] emitted from a radioactive source is

Correct answer

Step-by-step solution

In β - decay, energy emission is continuous and energy is shared between β - particles and daughter nuclei. Thus certain β -particles have zero energy and certain have maximum energy. Option (1) is most appropriate
