Resistance of a decimolar solution between two electrodes `0.02` meter apart and `0.0004m^(2)` in area was fround to be `50 ohm`. Specific conductance `(k)` is `:`

Options

A. `0.1Scm^(2)`
B. `1Scm^(2)`
C. `10Scm^(2)`
D. `4xx10^(-4)Scm^(2)`

Answer

B

Explanation

`G^(*)=(l)/(A)=(0.02)/(0.0004)=50m^(-1)`
`(1)/(R)=(1)/(50)`
Spacific conductance `G^(*)xx(1)/(R)=1Scm^(2)`
