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

  1. A4 m
  2. Bm 2
  3. C4 m 3
  4. D3 m

Correct answer

B. m 2

Step-by-step solution

W 1 W 2 = Q 1 Q 2 = I 1 × t 1 I 2 × t 2 m W 2 = 4 × 2 × 60 6 × 40 = 2 W 2 = m 2 g
