A $21$ cm long metal rod is oriented horizontally in a uniform magnetic field with magnetic flux density of $423$ G$.$ The magnetic field is directed vertically down into the ground. The metal rod is moved with a speed of $6$ m$/$s in a horizontal direction perpendicular to the length of the rod. Neglect the magnetic field of earth at the location of this apparatus. Determine the absolute value of the potential difference induced in the rod.

Calculate the answer in the units of volt $($V$).$

Write your answer in decimal form with three digits to the right of the decimal point $($e$.$g$.5\mathrm{.}374)$; do not write any units or sign.$$

Correct!
