A thin spherical shell made of plastic and Two large thin disks made of glass
A thin spherical shell made of plastic carries a uniformly distributed negative charge-7e-10coulombs (indicated as-Q1in the diagram). Two large thin disks made of glass carry uniformly distributed positive and negativecharges1.7e-05coulombs and -1.7e-05coulombs (indicated as +Q2and-Q2in the figure). The radiusR1of the plasticspherical shell is7mm, and the radiusR2of the glass disksis4meters. The distancedfrom the center of the spherical shell to the positive diskis18mm.
(a) Find the potential differenceV1-V2. Point 1 is at the center of the plastic sphere, and point 2 is just outside thesphere.
____volts
(b) Find the potential differenceV2-V3. Point 2 is just below the sphere, and point 3 is right beside the positive glassdisk.
____ volts
Remember that the sign of the potential difference is important.
