In figure a wire perpendicular to a long straight wire is moving parallel to the later with a speed  $\mathrm{\upsilon }=10\text{\hspace{0.17em}\hspace{0.17em}}\mathrm{m}/\mathrm{s}$ in the direction of the current flowing in the later. The current is 10A , what is the magnitude of the potential difference between the ends of the moving wire is  $2\times {10}^{-\mathrm{x}}$ ln (y)V then  $\frac{\mathrm{x}+\mathrm{y}}{5}=?$
