Final answer:
The electric potential at points in an xy plane is given by V = kQ/r. The electric potential V of a point charge is directly proportional to the magnitude of the charge Q and inversely proportional to the distance r from the point charge.
Step-by-step explanation:
The electric potential at points in an xy plane is given by V = kQ/r. The electric potential V of a point charge is directly proportional to the magnitude of the charge Q and inversely proportional to the distance r from the point charge.
For example, if a point charge has a larger magnitude of charge, the electric potential at points nearby will be greater. Similarly, if the distance from the point charge increases, the electric potential will decrease.
It's important to note that electric potential is a scalar quantity, meaning it only has magnitude and no direction. It is different from electric field, which is a vector quantity.
