6c) [2] Instead of the visor the driver could put the polarizer on the windshield of the race car. In this case what can you say about the polarizer (circle appropriate response/responses?) Should have polarizing axis vertical Should have polarizing axis horizontal Works best with light a normal incidence Depends on dispersion of the water on the road. Depends on the index of refraction of the windshield and the visor 7) [4] A vacuum capacitor (10cm radius plates with a 1mm separation) is charged with a 50mA current. Determine the magnetic field at the location shown, just outside the capacitor at a radius of 10.5cm
