**A Charged Isolated Conductor**

The electric field just above e the surface of the charged drum of a photocopy churner has a magnitude E What i the surface charge density on the drum. assuming that the drum is a conductor A uniformly charged conducting sphere of 1.1 m diameter has a surface charge density of 8.1 p.C/m (a) Find the net charge on the sphere. (b) What is the total electric flux leasing the surface of the sphere Space vehicles traveling through Earth’ s radiation belt can intercept a significant number of electrons The resulting charge buildup can damage electronic components and disrupt operation Suppose a spherical metallic satellite 1.3 m in diameter accumulate of charge in one orbital revolution (a) Find he resulting surface charge density (b) Calculate the magnitude of the electric field just outside the surface of the satellite. due to the surface charge An isolated conductor of arbitrary shape has a net charge f + lOX 10 Inside the conductor a cavity within his is a point charge q = + 3.0 X 10-(‘ e. What i, the charge a) on the cavity wall and (b) on the outer surface of the conductor.
