A student is interested in coating a metal surface of 675 $c{m}^2$ area with 0.004 mm thickness with silver by passing a current of 96.5 amp with 50% current efficiency through a silver nitrate aqueous solution. If the time required to complete the coating is ‘x’ seconds then calculate the value of $\frac{x}{10}$ .
(Given: Density of Ag is $10g/c{m}^3,$ atomic mass of Ag=108)
