RC-2 A half ring of charge lies in the x-z plane with its center at the origin as shown to the right. There are λ coulombs per meter of charge evenly distributed along the ring, which has radius 'a'. a) Sketch on your paper figures like the figures shown to the right. On your figures show an arrow representing the electric field at the point P that is produced by source charge element dq. b) Use Coulomb's law to calculate the magnitude of the x, y and z components of the total electric field at P due to the half ring of charge. If any component is equal to zero, you may use the symmetry argument to explain why it is zero instead of doing the calculations. 3D view: Z (C/m) X dq View looking from point P toward the origin: dq b a 9 y

A very long straight thread is oriented at right angles to an infinite conducting plane; its end is separated from the plane by a distance 1. The thread carries a uniform charge of linear density X. Suppose the point O is the trace of the thread on the plane. Find the surface density of the induced charge on the plane (a) at the point O. (b) as a function of a distance r from the point O.

The two sides of the DNA double helix are connected by pairs of bases (adenine, thymine, cytosine, and guanine). Because of the geometric shape of these molecules, adenine bonds with thymine and cytosine bonds with guanine. The figure (Figure 1) shows the thymine- adenine bond. Each charge shown is te, and the H-N distance is 0.110 nm

5. In the figure below, shows a Gaussian surface in the shape of a cube with edge length 1.40 m. What are (a) the net flux through the surface and (b) the net charge qenc enclosed by the surface if E = (3.00yj)N/C, with y in meters? What are (c) and (d) qenc if E = [-4.00i + (6.00 +3.00y)j] N/C?

A single square loop of wire is placed in the center of a large solenoid as shown. The solenoid has a radius 5.00 cm and the square loop is 3.0 cm on a side. The solenoid is 0.20 cm long and wound with 200 turns of wire. If the current in the solenoid is 3.00 A, what is the flux through the square loop? If the current in the solenoid drops to zero in 0.500 seconds, what is the magnitude of the average induced emf in the square loop?

A uniform electric field of magnitude 260 V/m is directed in the positive x direction. A +15.0 μC charge moves from the origin to the point (x, y) = (20.0 cm, 50.0 cm).
