** Keep in mind this is a line charge from z = a --> b, not a
point charge placed along the z axis.
7 Zab 2 a Iza BV A grounded conducting sheet is chosen as the xy-plane , where a cihcular regionof radius has been cutout, insulated, and raised to an electrostatic potential Vo. traddition, there is a uniform line charged along the z-axis (perpendicular to the plane and passing through the center of the disk) from z= a to z=b, as shown in the figure. Give the electrostatli potential (4,4, +7 at an 2) arbitrary, field point i = 2 x + 2y + ² E above the plane due to the disk; grounded plane and line change as an integral expussion, involving mo prietaisay pabols.
