A charge of -Q is uniformly distributed over the circumference of a circular segement of radius R located in the x-y plane. The circular segment spans the angles from pie/2 to pie, i.e., the second quadrant of the x-y plane. Point P is at the origin in the x-y plane. Find the electric potential at P. Please explain steps/concepts, draw a representation, and write clearly.
A charge Q is distributed uniformly around the perimeter of a ring of radius R. Determine the electric potential difference between the point at the center of the ring and a point on its axis at a distance 11R from the center. (Use any variable or symbol stated above along with the following as necessary: ke.) ΔV = V(0) − V(11R) =

5) A charge Q =-610 nC is uniformly distributed on a ring of 2.4-m radius. A point charge q = +480 nC is fixed at the center of the ring, as shown in the figure. An electron is projected from infinity toward the ring along the axis of the ring. This electron comes to a momentary halt at a point on the axis that is 5.0 m from the center of the ring. What is the initial speed of the...
Problem 6 Charge Q is uniformly distributed over a circular ring on the xy plane with an inner and outer radius a and b, respectively. Calculate the electric field at any point on the z axis by using Coulomb's law. Then, calculate the electric potential on the z axis and use this expression to find the z component of the electric field. Check that the electric field calculated through the potential is the same as the one calculated by using...
