[20 points] A single isolated point charge is carrying a charge q = 4 [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 r>r where ry is unknown. 1) [5 points] Find V₁, the electric potential on the surface of Sphere 1. V₁ - M 2) [10 points] If Sphere 2 is separated from Sphere 1 by a difference of potential AV-94.8 [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 (4-1.6 x 10-19) [C] from Sphere 2 to Sphere I considering that AV-94.8 [VI 10 Write an optional reasoning for your answer: -Sphere2 -Spherel 2 Z
