Self inductance || L-R Circuit

A wire of fixed length is wound on a solenoid of length l and radius r, its self inductance is found to be L. If same wire is wound on a solenoid of length l/3 and radius r/3 , then self inductance will be

If number of turns in a coil is quadrupled, then self-inductance will be:

The length l of a wire is shaped to form a coil of 1 turn. This coil has self inductance L. if the same length is bend more sharply to form 3 turns, the self inductance will become/remain

Two coils are made of copper wires of same length in the first coil the number turns is 3n and radius is r. In the second coil number of turns is n and radius is 3r the ratio of self inductances of the coils will be :-

How does self inductance of a coil depend on number of turns in the coil?

A solenoid have self inductance 2H. If length of the solenoid is double having turn density and area constant then new self inductance is :-
