Solution
The correct option is DCannotbedetermined We know that faraday's first law states that the Weight deposited is proportional to amount of charge. W = Z Q But remember that Q=I×t ⇒W=Z×I×t But we are not given the information for the amount of time the current was passed to determine the charge flowing through. So, the answer cannot be determined.
