A thin rod of length L with total charge Q lies along the x-axis and is centered at the origin. Please answer the following A. What is the electric field strength E at a point P located at position x? B. Does your expression have the expected behavior for x >> L? C. Evaluate E at x = 1.9 cm if L = 3.5 cm and Q = 17 nC.
Potential of a Finite RodA finite rod of length L has total charge q, distributed uniformly along its length. The rod lies on the x-axis and is centered at the origin. Thus one endpoint is located at (-L/2,0), and the other is located at (L/2,0). Define the electric potential to be zero at an infinite distance away from the rod. Throughout this problem, you may use the constant k in place of the expression .a) What is VA, the electric potential...

Point P is located at the center of one end of the cylinder, a distance d from the end of the wire. Point Q is on the edge of the cylinder directly above the center of the wire, as shown above. A student says, "Gauss's law...
A thin insulating rod has a uniform charge density along its length of -1.25 x 10°C/m. The rod is fixed in place on the y-axis, centered on the origin, and has a length of 4.80 cm. 1. Estimate the magnitude of the electric field produced by the charged rod on the positive x-axis 20.0 m from the origin. (Zero is not an acceptable estimate.) 2. State the direction of the electric field at the said point. Type both answers in...
