(B) According to Faraday's law of electrolysis,the mass deposited is $m = ZIt$,where $Z$ is the electrochemical equivalent of the substance.Since the substance is silver in both cases,$Z$ is constant.For the first case: $m_1 = m = Z \times 4 \times (2 \times 60) = 480 \ Z$.For the second case: $m_2 = Z \times 6 \times 40 = 240 \ Z$.Taking the ratio: $\frac{m_2}{m_1} = \frac{240 \ Z}{480 \ Z} = \frac{1}{2}$.Therefore,$m_2 = \frac{m_1}{2} = \frac{m}{2}$.
