Question

A delivery truck with 2.2-m-high aluminum sides is driving west at 55 km/hr in a region where the earth's magnetic field is B⃗ =(5.0×10−5T,north).

Part A What is the potential difference between the top and the bottom of the truck's side panels? Express your answer in volts. SubmitRequest Answer Part B Will the tops of the panels be positive or negative relative to the bottoms?

Answer 1

part-A for a conductor of length e, moving with velocity ŭ moving through uniform magnetic field B , the magnitude of induced e-mit is leinlall. (Tx B) here, the effective length is perpendicular to both ū which is towards went a ñ which is to words North, hence, leinla Bev ginen, basoiosa 2.2m tu= 55 km/h a) v = (55olovo) mis lein1= 5x10x2.2x55x1000 - 3600 - leinl = 1.680555556*1003 = 1.68 +103 (appron) = 1.68 mV (appron)

part-B since the truck is moving towards west t the magnetic field is towards north, rence all the negative changes o cie electrons) are accumulating at the top, hena, the tops of the panels will be negative relative to botton.
