The unit of self inductance of a coil is

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

Inductance of a solenoid is 3H and it consist of 500 truns . If number of turn make twice , then the value of self inductance becomes :

Assertion : When number of turns in a coil is doubled, coefficient of self-inductance of the coil becomes 4 times. Reason : This is because L prop N^(2)

On making a coil of copper wire of length  and coil radius r, the value of self inductance is obtained as L. If the coil of same wire, but of coil radius r/2, is made, the value of self inductance will be-
