[20 points] A single isolated point charge is carrying a charge q = 8 [nc]. As shown in the figure, two equipotential surfaces consist of two spheres centered on the point charge: Sphere 1 of radius r₁ = 1 [m]. → Sphere 2 of radius r₂>r where is unknown. 1) [5 points] Find V₁, the electric potential on the surface of Sphere 1. V₁=MV 2) [10 points] If Sphere 2 is separated from Sphere I by a difference of potential AV = 197 [V]. Find r2, the radius of Sphere 2 (Type the detailed solution to this question in the below box, Show all your calculation steps by typing in the box). 3) [5 points] Find the work required to bring an electron (q=-1.6 x 10-19) [C] from Sphere 2 to Sphere I considering that AV = 197 [V]. IJI Write an optional reasoning for your answer: -Sphere2 Sphere1 12
