SOLUTION

The inductance of transmission line is given by

$L = \dfrac{{{\mu _o}}}{\pi } \times \ln \left( {\dfrac{D}{{{r^\iota }}}} \right)$

Where

D = distance between the conductor

r’ = radius of the conductor

$L \propto \ln \left( {\dfrac{D}{{{r^\iota }}}} \right)$

Hence inductance is directly proportional to the distance between the conductor. If we increase the spacing between the conductors then inductance will also increase.
