Consider two infinite plates, both parallel to the xy plane of a coordinate system. The top plate is at the height z = +10cm and carries a uniform charge distribution of σ= +5nC/m2 . The bottom plate is at height z = - 10cm and carries a uniform charge distribution of σ= -5nC/m2.The space between the plates is filled with air.Between the plates runs a long wire along the x-axis (at y=0 and z=0), carrying a current of 7A. Two 1C test charges are moving between the plates. Test charge 1 moves in y-direction at a height of z = +3cm, at a speed of 4x10^6 m/s. Test charge 2 moves in x-direction at a height of z = -3cm, at a speed of 2m/s.
q1) Calculate the electric field between the plates and the magnitude and direction of the electric force FE exerted on each of the test charges due to that electric field.
q2) Calculate the magnitude and direction of the magnetic field caused by the current through the wire at the location of the test charges, and the magnitude and direction of the magnetic force FM exerted on each of the test charges due to that magnetic field.
q3) Combine the electric and magnetic forces to find the magnitude and direction of the total force on each of the test charges.
Consider that a 0.105 mm diameter tungsten filament in a light bulb needs to have a resistance of 0.25 Ω at 20.0°C. How long should the filament be in m, assuming the resistivity of tungsten is 5.60 x 10-8 Ω·m?
