Question

A proton, an electron, and a Helium nucleus, have the same energy. They are in circular orbitals in a plane due to magnetic field perpendicular to the plane. Let rₚ, rₑ and ʳHe be their respective radii, then,
(A) rₑ > rₚ = ʳHe (B) rₑ > rₚ > ʳHe (C) rₑ < rₚ < ʳHe (D) rₑ < rₚ = ʳHe

Answer 1

Answer:

c is the right answer

Answer 2

Answer:

(D) rₑ < rₚ = ʳHe. the correct answer.

Thanks for the question.......
