A) \[3\text{ }\times \text{ }{{10}^{20}}\]
B) \[3\text{ }\times \text{ }{{10}^{10}}\]
C) \[6\text{ }\times \text{ }{{10}^{20}}\]
D) \[6\text{ }\times \text{ }{{10}^{10}}\]
Correct Answer: A
Solution :
Amount of charge flows in 1 minute \[q=I\times t=1.6\times 60=96\,C\] Charge required to liberate one copper ion = 2C Number of \[C{{u}^{+2}}\] liberated \[=\frac{96}{2\times 1.6\times {{10}^{-19}}}=3\times {{10}^{20}}\]
