It's a question related to physics2 Unit: electric field
Can you please show the steps
Thanks, Chapter 22, Problem 022 Density, density, density. (a) A charge -307e is uniformly distributed along a circular arc of radius 5.50 cm, which subtends an angle of 40°. What is the linear charge density along the arc? (b) A charge -307e is uniformly distributed over one face of a circular disk of radius 4.70 cm. What is the surface charge density over that face? (c) A charge -307e is uniformly distributed over the surface of a sphere of radius 3.80 cm. What is the surface charge density over that surface? (d) A charge -307e is uniformly spread through the volume of a sphere of radius 3.90 cm. What is the volume charge density in that sphere? (a) Number Units (b) Number Units (c) Number Units (d) Number Units

Explanation / Answer

a) linear charge density = - 307 * 1.6 * 10-19/(0.698 * 0.055)

                                        = - 1.28 * 10-15 C/m

b) surface charge density = - 307 * 1.6 * 10-19/(3.14 * 0.047 * 0.047)

                                          = - 7.081 * 10-15 C/m2

c) surface charge density =   - 307 * 1.6 * 10-19/(4 * 3.14 * 0.038 * 0.038)

                                            =   - 2.708 * 10-15 C/m2

d) volume charge density =   - 307 * 1.6 * 10-19/(4/3 * 3.14 * 0.0393)

                                            = - 1.97 * 10-13 C/m3
