Answer:2
Explanation:
Given
Cable has twice the length of cable B
and twice the radius(both inner and outer) of cable B
Inductance is given by
Where l=length
r=inner radius
R=outer radius
=Permeability of inner cylinder
suppose 
and 
be the length of cable A and B
so 
for wire B
divide 1 and 2 we get
