Mixed He ⁺ and O ²⁺ ions (mass of He ⁺=4 amu and that of O ²⁺=16 amu ) beam passes a region of constant perpendicular magnetic field. If kinetic energy of all the ions is same, then
Options
- AHe ⁺ ions will be deflected more than those of O ²⁺
- BHe ⁺ ions will be deflected less than those of O ²⁺
- Call the ions will be deflected equally
- Dno ions will be deflected
Correct answer
C. all the ions will be deflected equally
Step-by-step solution
Radius of path of charged particle r= 2 m E_k B q E_k remains same, so aligned r₁ r₂ & = m₁ m₂ q₂ q₁ & = 4 16 2 1 = 1 2 2 1 = 1 1 aligned So, correct choice is (3).
