Consider the following arrangement of two conducting hollow spheres with a point charge of Qo = 3.90 UC at the center. The inner sphere has a Qo R2 radius of 0.011 m and carries a net charge of Q1= -2.30 UC. The outer sphere A has a radius of 0.061m and carries a net charge of Q2 = 6.70 UC. Calculate the magnitude of the electric field at point A located at a distance 0.021 m from the center. Submit Answer Tries 0/12 Calculate the surface charge density on the outer surface of the outer sphere. Neglect the thickness of the sphere. Submit Answer Tries 0/12
