A very long straight thread of length L carries a charge Qspread uniformly along its length. What is the magnitude of theelectric field at a radial distance r from the thread? Hint:consider a gaussian cylinder concentric with the thread.
a) E = Q/2πεoL2

b) E = Q/2πεor2

c) E = Q/4πεorL

d) E = Q/4πεor2

A solid insulating sphere of radius a = 5.00 cm carries a net positive charge of Q = 3.00 μc uniformly distributed throughout its volume. Concentric with this sphere is a conducting spherical shell with inner radius b =10.0 cm and outer radius c= 15.0 cm as shown in Figure P24.54, having net charge q= 1.00 μc Prepare a graph of the magnitude of the electric field due to this configuration versus r for 0 < r < 25.0 cm.

A solid insulating sphere of radius a = 5.00 cm carries a net positive charge of Q = 3.00 μC uniformly distributed throughout its volume. Concentric with this sphere is a conducting spherical shell with inner radius b = 10.0 cm and outer radius c = 15.0 cm as shown in Figure P24.54, having net charge q = −1.00 μC. Prepare a graph of the magnitude of the electric field due to this configuration versus r for 0 < r < 25.0 cm.
