Two coils A and B have 200 and 400 turns respectively. A current of 1 A in coil A causes a flux per turn of `10^(-3)` Wb to link with A and a flux per turn of `0.8xx10^(-3)` Wb through B. the ratio of mutual inductance of A and B is

A current of 3A, in one coil, causes a flux in the second coil of 2000 turns to change by 6xx10^(-4)Wb per turns of the secondary coil. The mutual inductance of the pair of coils is

Two coils A and B having turns 300 and 600 respectively are placed near each other, on passing a current of 3.0 ampere in A , the flux linked with A is 1.2xx10^(-4) and with B it is 9.0xx10^(-5) weber. The mutual inductance of the system is
