Document Summary
Phy1122 a discussion group march 4, 5 2015. Charge of uniform density (40 pc/m2) is distributed on a spherical surface (radius. = 1. 0 cm), and a second concentric spherical surface (radius = 3. 0 cm) carries a uniform charge density of 60 pc/m2. What is the magnitude of the electric field at a point 4. 0 cm from the center of the two surfaces: 3. 8 n/c, 4. 1 n/c, 3. 5 n/c, 3. 2 n/c, none of the above. Three hollow, concentric spherical conductors are charged as follows: the inner sphere carries charge q, the middle sphere carries charge 2q, the outer sphere carries charge q. What is the charge on the outer surface of middle sphere: q, +q, +2q, 2q, none of the above. A positive point charge q is placed outside a large neutral conducting sheet. At any point in the interior of the sheet the electric field produced by charges on the surface is directed.
