A) \[8\]
B) \[80\]
C) \[10\]
D) \[16\]
Correct Answer: A
Solution :
: \[\omega =Z\times I\times t\] \[30=\frac{Eq.\,wt}{96500}\times 5\times t\] Eq. \[wt=\frac{40}{2}\] \[[C{{a}^{2+}}+2{{e}^{-}}\xrightarrow{{}}Ca]\] \[30=\frac{40}{2\times 96500}\times 5\times t\] \[t=\frac{30\times 2\times 96500}{40\times 5}\] \[t=28950\,\,s=\frac{28950}{3600}=8hours\]
