1. The problem statement, all variables and given/known data A point charge is at the center of a conducting hollow sphere, with radius 0.011m, that is within another conducting hollow sphere of radius 0.041m. The point charge is Q0=+4.30e-6 C, the inner sphere has a net charge of Q1=-1.70e-6 C, and the outer sphere has a net charge of Q2=+6.50e-6 C. Calculate the magnitude of the electric field at a point A located 0.021m from the center. 2. Relevant equations Gauss' Law [tex]\Phi[/tex]= Qin/ [tex]\epsilon[/tex] = E*Areas Areas=4[tex]\pi[/tex]r2 [tex]\epsilon[/tex]=permittivity constant 3. The attempt at a solution I've been stuck on this for awhile and don't really know where to begin. I know point A is between the two hollow spheres, one of which is positive, the other negative. But I don't know what to think of the conducting spheres when they aren't in electrostatic equil because they dont have net Q=0. Will the E of point A just be the sum of the electric fields of the spheres and point charge? EA= E0+E1+E2?
