The "Potential from Center of Disk" refers to the electric potential at any point around a charged disk, measured from its center. It is a measure of the work required to move a unit positive charge from infinity to that point while keeping it at rest.
The potential at a point from the center of a disk is determined by the distance from the center of the disk, the magnitude of the charge on the disk, and the electric constant. It can be calculated using the equation V = kQ/r, where V is the potential, k is the electric constant, Q is the charge on the disk, and r is the distance from the center of the disk.
The potential from the center of a disk is affected by the magnitude of the charge on the disk, the distance from the center of the disk, and the electric constant. It is also affected by any other nearby charges or conductors, which can alter the electric field and thus the potential at a particular point.
The potential from the center of a disk is calculated using the distance from the center of the disk, whereas potential from a point charge is calculated using the distance from the point charge. Additionally, the electric field from a disk is not constant, unlike that of a point charge, which can affect the potential at different points around the disk.
The potential decreases as you move farther away from the center of the disk, following an inverse relationship with the distance. This means that the potential will decrease at a faster rate as you move away from the center. This is due to the decrease in electric field strength as you move away from the charged disk.
