A spherical cavity of radius a is within a large, grounded conductor. A charge q is placed within the cavity at a distance b from the center. a) Find the potential at all points within the cavity. Use spherical coordinates with origin at the center and z axis passing through q. b) Find the electric field, E vector at all points within the cavity. What is E vector at the center of the cavity

if you answer my question i will answer yours

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
