A particle of mass

m

moves in a circular orbit in a central potential field

U(r)=U_0 r^4

. If Bohr's quantization conditions are applied, radii of possible orbitals

r_n

vary with

n^{1 / \alpha}

, where

\alpha

is ......

View answer and explanation

Correct option: A

Option A (3) is correct because by applying Bohr's quantization condition and the given potential, the radius

r

is proportional to

n^{1/3}
