what formula do we use to find the number of electrons when given total charge (q)?
The charge for Q3 is not given. I could not find formula in book. So do I take EA total 4.5 X 10^6 N/C. And use it for E? Then set formula like so 4.5 X 10^6= (9.0x10^9)Q/(.30m)^2 and solve for Q to get charge? I need help. ple 16-9, but calculate the electric field (magnitude and direction) at Q1 due to the Rework Exam other two charges. EXAMPLE 16-9 E above two point charges. Calculate the total ele field...

When we find the electric field due to a continuous charge distribution, we imagine slicing that source up into small pieces, finding the electric field produced by the pieces, and then integrating to find the electric field. Let's see what happens if we break a finite rod up into a small number of finite partides. The figure below shows a rod of length 2 carrying a uniform charge Q modeled as five particles of charge Q/5. Two particles are at...
A solid, insulating sphere of radius a has a uniform charge density throughout its volume and a total charge of Q. Concentric with this sphere is an uncharged, conducting hollow sphere whose inner and outer radii are b and c as shown in the figure below. We wish to understand completely the charges and electric fields at all locations. (Assume Q is positive. Use the following as necessary: Q, ε0 , a, b, c and r. Do not substitute numerical...
