Question

Can you explain the steps and how did you do it? That would be helpful! Thanks. A delivery truck with 2.8 m high aluminum sides is driving west at 75 km/hr in a region where the earth's magnetic field is B = 5.0 x 10-5T, North. (a) What is the potential difference between the top and the bottom of the truck's side panels? (0.0029 v) (b) Will the tops of the panels be positive or negative relative to the bottoms? (use the rule, find the direction of force on positive charge, positive charges would be pushed in the direction of the force)

Explanation / Answer

The bottom is positive
And V = v*B*L = 75km/hr*1000m/km*1hr/3600s*5.0x10^-5*2.8 = 0.0029 V
