Cathode ray tubes in old television sets worked by accelerating electrons and then deflecting them with magnetic fields onto a phosphor screen. The magnetic fields were created by coils of wire on either side of the tube carrying large currents. In one such TV set, the phosphor screen is 48.4 cm wide, and is 10.1 cm away from the center of the magnetic deflection coils (that is, the center of the region of magnetic field). The electron beam is first accelerated through a 10,000 V potential difference before it enters the magnetic field region, which is 1.00 cm wide. The field is approximately uniform and perpendicular to the velocity of the electrons. If the field were turned off, the electrons would hit the center of the screen. What magnitude of magnetic field (in mT) is needed to deflect the electrons so that they hit the far edge of the screen? Ignore any relativistic corrections. mT

Potential in a charge distribution 3 points We have a sphere with diameter d = 7 m and charge density profile ρc(r) = Ar2ω where A = 6×10−8. The change in potential energy of a charge q = 5 mC moved from a radius of r = 2.3 m inside the sphere to the very edge of the sphere was found to be −25 J. Find the value of the constant ω. (Next three questions) We have a spherical ball in a vacuum with three layers: the center and outer layers have constant charge density ρ = 0.7 μC/m3 and the middle layer is a perfect conductor. We'll define zero potential, V = 0, at an infinite distance away from the sphere. The radii are a = 0.3 m, b = 0.7 m, and c = 1 m. Figure 3: Figure for Problems 9-11 Potential at purple dashed line 1 point (a) What is the potential at r = 0.4 m away from the center of the sphere (purple dashed line)? (number 10) Potential at yellow dashed line 1 point What is the potential at r = 0.85 m away from the center of the sphere (yellow dashed line)? (number 11) Potential at green dashed line 1 point What is the potential at r = 1.2 m away from the center of the sphere (green dashed line)?

Assume current flows in a cylindrical conductor in such a way that the current density increases linearly with radius, from zero at the center to 1.0 A/m^2 at the surface of the conductor. If the conductor has a cross sectional area of 1.0 m^2, what can you say about the current in this conductor? The current is more than 1.0 A. The current is less than 1.0 A. The current is 1.0 A. Any of these choices might be correct.
