The Attempt at a Solution
Assuming zero of the potential is at infinity , the potential refers to the potential difference between the each conductor and infinity .
The potential of the uncharged conductor would be due to three charges, positive induced charge , negative induced charge and positively charged conductor . Now contribution of the potential due to charged conductor would be less as compared to its contribution on the charged conductor itself .
Due to proximity of negative induced charges to the charged conductor , its potential ( charged conductor ) will be less as compared to the situation if uncharged conductor was not present .
So , how should I compare the potentials of the two conductors .
