The inner radius of a spherical insulating shell is 14.6 cm, and the outer radius is 15.9 cm. The shell carries a charge of 4.20 ×10-8 C, distributed uniformly through its volume. Sketch, for your own benefit, the graph of the potential for all values of r (the radial distance from the center of the shell). Letting the potential be zero at infinity, what is the potential at the center of the shell (r = 0)? =\ אני לא מבינה מה הם רוצים ניסיתי לשרטט והתשובה שלי לא נכונה אין לי כיוון..
