A metal sphere centered at the origin has a surface charge density that has a magnitude of 24.9 nC/m2 and a radius less than 2.00 m. At a distance of 2.00 m from the origin, the electric potential is 530 V and the electric field strength is 265 V/m. (Assume the potential is zero very far from the sphere.) What is the radius of the metal sphere?

A conducting sphere with radius R is centered at the origin. The sphere is grounded having an electric potential of zero. A point charge Q is brought toward the sphere along the z- axis and is placed at the point ะ-8. As the point charge approaches the sphere mobile charge is drawn from the ground into the sphere. This induced charge arranges itself over the surface of the sphere, not in a uniform way, but rather in such a way...

Tangent plane to a sphere: Consider the sphere of radius R centered on the origin in 3 dimensions. Now consider the point o = Doi+yoj + zok. Write the equations for any two (non-parallel) planes which pass through both the point to and the origin. Using these planes, write the equation for the tangent plane of the sphere at the point to. (Hint: think about how the tangent plane of a sphere must be perpendicular to a line connecting the...

A hollow sphere of radius a has uniform
surface charge density σ and is centered at the origin. It
sits inside a bigger sphere, also centered at the origin, with
radius b > a and uniform
surface charge density −σ. Because of the spherical
symmetry, the electric field will have the form () =
E(r) r̂, where
negative E(r) corresponds to an
electric field pointing towards the origin, and positive
E(r) corresponds to a field
pointing away. What is E(r)...
A spherical shell centered at the origin has an inner radius of 4 cm and an outer radius of 6 cm.
A spherical shell centered at the origin has an inner radius of 4 cm and an outer radius of 6 cm. The density, δ, of the material increases linearly with the distance from the center. At the inner surface, δ = 9 g/cm3; at the outer surface, g = 13 g/cm3 (a) Using spherical coordinates, write the density, δ, as a function of radius, p. (Type rho for ρ) (b) Write an integral in spherical coordinates giving the mass of the shell (for...
