Mass of Cu and Ag deposited will be different
Explanation:
The mass of Cu and Ag deposited on the cathode will be different. According to Faraday's second law of electrolysis, amount of different substance liberated by same quantity of electricity passed through the electrolyte solution is directly proportional to their chemical equivalent weight.
W1 / W2 = E1 / E2
E1 and E2 are different values which depends upon the number of electrons required to reduce the metal ion.
