A monopole in terms of electric potential refers to a single point charge that creates an electric field. It is also known as a point charge or a scalar charge.
A dipole in terms of electric potential refers to two equal and opposite point charges that are separated by a small distance. This creates an electric field that is stronger near the charges and weaker in between them.
To calculate the electric potential on a half disk, you can use the equation V = kQ/r, where k is the Coulomb's constant, Q is the charge of the disk, and r is the distance from the center of the disk to the point where the potential is being measured.
The electric potential on a half disk varies depending on the distance from the center of the disk. It is strongest near the center and decreases as you move away from the center.
Understanding the monopole and dipole terms of electric potential on a half disk is important in understanding the behavior of electric fields and how they interact with charges. It also helps in calculating the electric potential at different points on the disk, which can be useful in various applications such as in designing electrical circuits and devices.
