You move from location at to location at . All along this path there is a nearly uniform electric field of . Calculate , including sign and units.
What are the units of electric potential energy, of electric potential, and of electric field?
A capacitor consists of two large metal disks placed at a distance apart. The radius of each disk is , and the thickness of each disk is, as shown in Figure 16.73. The disk on the left has a net charge of, and the disk on the right has a net charge of. Calculate the potential difference , where location 1 is inside the left disk at its center, and location 2 is in the center of the air gap between the disks. Explain briefly
A dipole is centered at the origin, with its axis along the y axis, so that at locations on the y axis, the electric field due to the dipole is given by
The charges making up the dipole are and , and the dipole separation is (Figure 16.82). What is the potential difference along a path starting at location and ending at location ?
Locationsare on the +x axis, as shown in Figure 16.61. Four possible expressions for the electric field along the x axis are given below. For each expression for the electric field, select the correct expression (1鈥�8) for the potential difference. In each case K is a numerical constant with appropriate units.
