A conducting sphere of radius 0.01m has a charge of deposited on it. The magnitude of the electric field in N/C justoutside the surface of the sphere is:
A spherical cavity is hollowed out of the interior of a neutral conducting sphere. At the center of the cavity is a point charge,of positive charge q.
A) What is the total surface charge q on the interior surface of the conductor (i.s., on the wall of the cavity)?
C) What is the magnitude of the electric field inside the cavity as a function of the distance from the point charge? Let k, as usual, denote .
D)Will the total charge on the surface of the cavity change?
Will the totaly charge on the exterior of the conductor change?
Will the charge on the electric field with in the cavity change?
Will the charge on the electric field outside the cavity change?
