R P In the figure above a semi-infinite nonconducting rod (that is, infinite in one direction only) has uniform linear charge density X. NOTE: Use a standard ry coordinate system with a to the right and y upward, and express your answers to parts (a) and (b) in terms of R, A, and (a) Determine the x component of the electric field at point P. (b) Determine the y component of the electric field at point P. y 3= (c) Determine the counterclockwise angle 0 that the electric field makes with the +x axis. Unit= Choose one %3D

A positively charged disk of radius R and total charge Qdisk lies in the xz plane, centered on the y axis (see figure below). Also centered on the y axis is a charged ring with the same radius as the disk and total charge Qring: The ring is a distance d above the disk. Determine the electric field at the point P on the y axis, where P is above the ring a distance y from the origin. (Use any variable or symbol stated above along with the following as necessary: k.) magnitude E = direction ---Select--- y P R

The figures show cross sections of three-dimensional closed surfaces. They have a flat top and bottom surface above and below the plane of the page. However, the electric field is everywhere parallel to the page, so there is no flux through the top or bottom surface. The electric field is uniform over each face of the surface. Figure 10 N/C 10 N/C 10 N/C ▾ Part B For (Figure 2), does the surface enclose a net positive charge, a net negative charge, or no net charge? Match the words in the left column to the appropriate blanks in the sentences on the right. Submit an outward an inward zero no net charge a net negative charge a net positive charge There is flux through each side of the surface, which indicates that there is enclosed in this surface.

la Given A = 17 [80°] and B = 13 [159°], the cross product B x A is Round your answer to the nearest tenth and make sure to include the sign if your answer is in the negative z-direction. Your Answer: Answer b Several point charges are located within a closed Gaussian surface, S, and several point charges are located just outside of the Gaussian surface. The magnitude of each charge is equal q and the number of positive and negatives charges in each of the respective regions are shown below. What is the electric flux, E = f. Ē · dã, given by Gauss' law through the closed surface S? Not uniform along S as the charge is not uniform A line of charge with linear charge density i = 29 nC/m is enclosed in a Gaussian cylinder with height h = 18.2 mm and radius r = 4.3 mm as shown below. What is the magnitude of the total electric flux passing through the cylinder in Nm2/C? Round your answer to the nearest whole number. Your Answer:
