OK so here is my attempt to the problem: A) EA = (Qin/ε) (volume ratio) E (4(pi)r1^2) = (Q1/ ε) ((4/3 pi r1^3)/(4/3 pi r2^3)) E (4 pi r1^2) = Q1 r1^3 / ε r2^2 E= Q1 r1^3 / ε r2^3 4pi r1^2 E = Q1 r1 / 4pi ε r2^3 E = KQ1 r1 / r2^3 final answer for a B) v= kQ1/r1 + kQ2/r2 V = (9 x 10^9...

Homework Statement Given two things spherical shells radii r1 and r2 with r2 > r1. The inner she'll is charged uniformly with a total charge Q1, while the outer shell with Q2. A) use gauss law to computer the electric field everywhere B) Use any method to calculate the potential everywhere...

Homework Statement Given two very long lines each is charged with linear density +lambda Coulombs/meter. The two lines are separated by a distance of d metres. A) show the electric field E, at any point along one of the lines due to the other line is E = lambda/(2 (pi)(epsolon o)(d)) (Note...
