(II) A nonconducting sphere is made of two layers. The innermost section has a radius of 6.0 cm and a uniform charge density of –5.0 C/m 3 . The outer layer has a uniform charge density of +8.0 C/m 3 and extends from an inner radius of 6.0 cm to an outer radius of 12.0 cm. Determine the electric field for ( a ) 0 < r < 6.0 cm. ( b ) 6.0 cm < r < 12.0 cm, and ( c ) 12.0 cm < r < 50.0 cm. ( d ) Plot the magnitude of the electric field for 0 < r < 50.0 cm. Is the field continuous at the edges of the layers?

On the x-y plane, a point charge Q = –4.35E-6 C is placed at the origin (0.00 m, 0.00m). The electric field at (x,y) = (2.40 m, 3.20 m) is measured to be Q = Ex + Ey . What is the electric field's y componentEy (in N/C)?
A uniform charge of 16.0 mC is on a thin circular ring lying in an xy plane and centered on the origin.The ring’s radius is 3.00 cm. If point A is at the origin and point B is on the z axis at z = 4.00 cm, what is VB - VA?
This equation is for the electric field of a uniform ring which is charged and is at point z which is perpendicular to the center of the ring. (it means z=0 is part of the plane in which the ring is in).
R=radius of ring, Q= total charge of ring, k= coulomb's constant.
If k=1 units, Q=1 units, R=8 units, what is Ering, z when z=6 units?
