ELECTRIC AND MAGNETIC FIELDS

THIS PROBLEM DEALS WITH ELECTRIC AND MAGNETIC FIELDS HOWEVER I DON'T KNOW WHAT THEY MEAN ABOUT AN INSTANT IN THE CONSEQUENT CORNERS. PLEASE EXPLAIN TO ME HOW TO DO THIS PROBLEM STEP BY STEP SO THAT I WILL BE ABLE TO UNDERSTAND PROBLEMS THAT ARE SIMILAR

Work done in assembling a solid charged sphere of uniform charge density

(a) Calculate the work done in bringing a charged spherical shell of thickness dr from infinity up to enclose an existing charged sphere of radius r, both having uniform charge densities. (b) Integrate this expression to calculate the work done U, in assembling a solid sphere of radius 'a' of uniform charge density. U = 3kQ ...continues

Solid insulation sphere of non-uniform charge density. Finding the electric field in side the sphere using Gauss' law: (a) Consider a solid insulating sphere of radius b with non-uniform charge density s= ar, where 'a' is a constant. Find the charge Q_r contained within the radius r, when r < b. (b) If a = 2 x 10^-6 C/m^4 and b= 1 m, find the electric field, E at r= 0.6 m. Answer in units of N/C.

Please review the attached conceptual physics questions. Instead of just the answers, I would also like full explanations. This is so I can learn the material. Please make sure you are accurate and clear. Thanks. Please See attached word document

Induced Voltages and Inductance

1.) Transcranial magnetic stimulation (TMS) is a noninvasive technique used to stimulate regions of the human brain. A small coil is placed on the scalp, and a brief burst of current in the coil produces a rapidly changing magnetic field within the brain. The induced emf can be sufficient to stimulate neuronal activity. One such ...continues

RC

10. [SerPOP4 21.P.043.] In the circuit of Figure P21.43, the switch S has been open for a long time. It is then suddenly closed. Determine the time constant before and after the switch is closed. (R = 120 kilo ohms.)
