Question

A particle of mass m moves in a circular orbit in a central potential field U(r) = (1/2)kr² . If Bohr’s quantization conditions are applied, radii of possible orbits and energy levels vary with quantum number n as:
(A) rₙ ∝ √(n) , Eₙ ∝ n (B) rₙ ∝ √(n) , Eₙ ∝ 1/n
(C) rₙ ∝ n , Eₙ ∝ n (D) rₙ ∝ n² , Eₙ ∝ 1/n²
