In the figure find the potential difference across R2 if ε = 11.3 V, R1 = 5.66 Ω, R2 = 9.04 Ω, and R3 = 5.02 Ω.

The figure shows a thin plastic rod of length L = 13.1 cm and uniform positive charge Q = 51.9 fC lying on an x axis. With V = 0 at infinity, find the electric potential at point P1 on the axis, at distance d = 2.63 cm from one end of the rod.

A charge of uniform linear density 2.00 nC/m is distributed along a long, thin, nonconducting rod. The rod is coaxial with a long conducting cylindrical shell (inner radius = 6.00 cm, outer radius = 10.0 cm). The net charge on the shell is zero. What is the magnitude of the electric field at distance r = 16.0 cm from the axis of the shell? 

You are to connect capacitances C1 and C2, with C1 > C2, to a battery, first individually, then in series, and then in parallel. Rank those arrangements according to the amount of charge stored, greatest first.

A client is transferred from the post anesthesia care unit (PACU) to the clinical unit. Which action by the nurse on the clinical unit should be performed first?

A beam contains 8.1 × 107 doubly charged positive ions per cubic centimeter, all of which are moving north with a speed of 3.6 × 105 m/s. What is the magnitude of the current density?

An electron with a speed of 6.57 × 108 cm/s in the positive direction of an x axis enters an electric field of magnitude 1.90 × 103 N/C, traveling along a field line in the direction that retards its motion. How far will the electron travel in the field before stopping momentarily?

A nonuniform linear charge distribution given by λ = bx, where b is a constant, is located along an x axis from x = 0 to x = 0.30 m. If b = 53 nC/m2 and V = 0 at infinity, what is the electric potential at the origin?
