Two voltmeters, one of copper and another of silver, are joined in parallel. When a total charge qqq flows through the voltmeters, equal amount of metals are deposited. If the electrochemical equivalents of copper and silver are Z1{Z_1}Z1​ and Z2{Z_2}Z2​ respectively the charge which flows through the silver voltmeter is
