The smiling face of the figure consists of three items: a thin rod of charge −4.50 μC that forms a full circle of radius 9.00 cm; a second thin rod of charge 3.00 μC that forms a circular arc of radius 6.00 cm, subtending an angle of 90∘ about the center of the full circle; an electric dipole with a dipole moment that is perpendicular to a radial line and has magnitude 1.94×10−21 Gm. What is the net electric potential at the center? Number Units

J. J. Thomson is best known for his discoveries about the nature of cathode rays. His other important contribution was the invention, together with one of his students, of the mass spectrometer, a device that measures the ratio of mass m to (positive) charge q of an ion. The spectrometer consists of two regions as shown in the figure. (Figure 1) In the first region an electric field accelerates the ion and in the second the ion follows a circular arc in a magnetic field. The radius of curvature of the arc can be measured and then the m/q ratio can be found. Figure 1 of 1 After being accelerated to a speed of 1.69×105 m/s, the particle enters a uniform magnetic field of strength 0.900 T and travels in a circle of radius 35.0 cm (determined by observing where it hits the screen as shown in the figure). The results of this experiment allow one to find m/q. Find the ratio m/q for this particle. Express your answer numerically in kilograms per coulomb. View Available Hint(s)

The figure is a section of a conducting rod of radius R1 = 1.30 mm and length L = 13.40 m inside a thin-walled coaxial conducting cylindrical shell of radius R2 = 11.3R1 and the (same) length L. The net charge on the rod is Q1 = +3.50×10−12 C; that on the shell is Q2 = −2.08Q1. What are the (a) magnitude E and (b) direction (radially inward or outward) of the electric field at radial distance r = 2.08R2? What are (c) E and (d) the direction at r = 5.16R1? What is the charge on the (e) interior and (f) exterior surface of the shell? (a) Number Units (b) (c) Number Units (d) (e) Number Units (f) Number Units
