The velocity of an electron in the ground state of a hydrogen atom is VH. If Vp be the velocity of an electron in the ground state of positronium, thena)Vp= VHb)Vp=2Vhc)d)Correct answer is option 'A'. Can you explain this answer?

Question

Answer

H-atom having one electron in its ground state. So. having V_H velocity and positronium is the electron category, that is a particle having mass equal to electron but charge opposite in nature and same magnitude.
q_p = 1.6 x 10^-19c
M_p = 9.1 x 10^-31kg
So, velocity of positronium (V_p) is equal to the velocity of electron in H-atom V_H
V_p = V_H

Answer

H-atom having one electron in its ground state. So. having V_H velocity and positronium is the electron category, that is a particle having mass equal to electron but charge opposite in nature and same magnitude.
q_p = 1.6 x 10^-19c
M_p = 9.1 x 10^-31kg
So, velocity of positronium (V_p) is equal to the velocity of electron in H-atom V_H
V_p = V_H
