In the process electroplating, m g of silver is deposited when 4 ampere of current flows for 2 minutes. The amount (in g) of silver deposited by 6 ampere of current flowing for 40 sec will be

Options:

Answer:

Solution:

$\frac{W_{1}}{W_{2}} = \frac{Q_{1}}{Q_{2}} = \frac{I_{1} \times t_{1}}{I_{2} \times t_{2}}$
$\frac{m}{W_{2}} = \frac{4 \times 2 \times 60}{6 \times 40} = 2$
$W_{2} = \frac{m}{2} g$
