Question 3 Not yet answered Marked out of 20.00 Flag question [20 points] A single isolated point charge is carrying a charge q = 1 [nc]. As shown in the figure, two equipotential surfaces consist of two spheres centered on the point charge: Sphere 1 of radius r₁ = 9 [m]. Sphere 2 of radius r2 >r where r2 is unknown. 1) [5 points] Find V₁, the electric potential on the surface of Sphere 1. V₁ = [V] 2) [10 points) If Sphere 2 is separated from Sphere I by a difference of potential AV-2,05 [V]. Find r, 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). q -Sphere2 Sphere1 NT ********* 3) (5 points) Find the work required to bring an electron (4.-1.6 x 10-19) [C] from Sphere 2 to Sphere 1 considering that AV=2.05 [V].
