(b) Find the potential difference V2 - V3. Point 2 is just below the sphere, and point 3 is right beside the positive glass disk.

Q2 -Qi R << R2 +Q2 R2 (not to scale) A thin spherical shell made of plastic carries a uniformly distributed negative charge -5e-10 coulombs (indicated as -Q, in the diagram). Two large thin disks made of glass carry uniformly distributed positive and negative charges 1.5e-05 coulombs and -1.5e-05 coulombs (indicated as +Q, and -Q, in the figure). The radius R, of the plastic spherical shell is 7 mm, and the radius R, of the glass disks is 4 meters. The distance d from the center of the spherical shell to the positive disk is 18 mm. (a) Find the potential difference V1 - V2. Point 1 is at the center of the plastic sphere, and point 2 is just outside the sphere. |-236.04 (b) Find the potential difference V, - V3. Point 2 is just below the sphere, and point 3 is right beside the positive glass disk. volts X volts Remember that the sign of the potential difference is important.
