Consider a disk of radius R = 41.0 cm and thickness t = 1.1 cm, with a nonuniform volume charge density given by ? = A r (with r the distance from the center of the disk).

If A = 510 ?C/m4, what is the total charge of this disk?

Q = ?C

If instead the total charge is Q = 1.26 ?C, what is the value of the constant A?

A = ?C/m4
