Astrip of copper 370 μm thick and 4.5 mm wide is placed in a uniform magnetic field b with arrow of magnitude 0.30 t, with b with arrow perpendicular to the strip. a current i = 24 a is then sent through the strip such that a hall potential difference v appears across the width of the strip. calculate v. (the number of charge carriers per unit volume for copper is 8.47 ✕ 1028 electrons/m3.)

Explanation:

The given data is as follows.

              Magnetic field (B) = 0.30 T

              Current (I) = 24 A

              n =

            charge on electron (e) = C

Formula to calculate the potential difference is as follows.

            V =

                =

                = V

Therefore, we can conclude that value of potential difference is V.

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.
