Question

Consider aimimg a beam of free electrons to wards free atoms . When they scatter, an electron and a protons cannot combine be produced a H-atom,
A. beacause of energy conservation
B. with simulataneously releasing energy in the form or radiation .
C. because of momentum conservation
D. because of angular momentum conservation .

Answer 1

Correct Answer - A::B
When a beam of gree electron is aimed to towards free protons, the electron get `5t` scattered on ac-count of energy conservation . An electron and a proton can combine to produce ga H-atom only if they simulataneously relase energy in the form of radiations.
