**Unformatted text preview: **of +q from X to Y, is the work done by the electric field due to the rod positive, negative, or zero? Give a reason for your answer. Q2 = 8x10-6 C Q1 = 6x10-6 C 0.3 m 0.4 m 0.4 m B A 0.3 m Q3 = 8x10-6 C 0.5x10-6 C 7x10-6 C 2m Y X 4. For a point charge, we derived an expression from Gauss’s law for the electric field a distance r away. You have a point charge of +2q centered in a conductive spherical shell of inner diameter a and outer diameter b. You place +8q on the spherical shell. Find the following: a. What is the electric field for r<a? b. What is the electric field for a<r<b? c. What is the electric field for r>b? d. What is the CHARGE on the inner radius of the shell?...
