Answer the following by appropriately matching the lists based on the information given in the paragraph.
Consider the Bohr’s model of a one – electron atom where the electron moves around the nucleus. In the following List – I contains some quantities for the nth orbit of the atom and List – II contains options showing how they depend on n

List I	List II
I) Radius of the nth orbit	P) ∝n−2
II) Angular momentum of the electron in the nth orbit	Q) ∝n−1
III) Kinetic energy of the electron in the nth orbit	R) ∝n0
IV) Potential energy of the electron in the nth orbit	S) ∝n1
	T) ∝n2
	U) ∝n1/2

Which of the following options has the correct combination considering List – I and List – II?
