Solution

The correct option is B $0.0413$ V
For a concentration cell as the anode and cathode are of the same elements the $E_{c e l l}^{0} = 0$ .
Nernst equation is,

$E_{c e l l} = E_{c e l l}^{0} - \frac{0.0591}{n} l o g Q$

It becomes,

$E_{c e l l} = 0 - \frac{0.0591}{1} l o g \frac{0.01}{0.05}$

$= 0.0413 V$
