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.

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.
