I always get confused in distinguish between ( conductor sphere and insulator sphere ) !!
what is location of charges ( only on the surface , throughout the volume , or both of them ) ?
Is E zero inside the conductor sphere ?
IF we have the both kind of spheres ( same radius ) , which one will hase the bigger capacitance ( C )
Condcutor has a availability of large no. of free electrons
charges are didtributed through out the Volume
while in insulators there are no free electrons
------------------------------
No, EF is nor zero inside the conductor
Capacitance is given by the formula C = 4pi eo R
so C is depening on R ans its Value is more fo conductor than insulator

(a) We have said that Gauss’s law is always true, but only useful for calculating the electric field created by source charge distributions that are spheres, infinite straight cylinders, and infinite flat sheets, and even those cases have additional restrictions. Explain why we are limited to those distributions. Discuss what additional restrictions apply. For example, can we use Gauss’s law to find the field of a sphere whose density depends on distance r from the center? Can we do it...
Select Tru or False. 1. A conducting sphere with charge Q at equilibrium has zero E field inside it. The E field outside is the same as that of a point charge Q, E=keQ/r2. The potential outside it is the same as that of a point charge Q. V= keQ/r. (r is the distance to the center). The potential inside the conducting sphere is equal to the potential at its surface. V= keQ/R. (R is the radius of the sphere)...
This is a cross section of two nested spheres. The outer sphere is a thin conductor of radius M with a uniform charge distribution and total excess charge of-20. The inner sphere is a solid insulator of radius J. It has a uniform volume charge density of p and a total charge of +2Q. There is only vacuum between them. Region C +2Q,+p 1.)

For a charged solid metal sphere with total charge Q and radius R centered on the origin: Select "True" or "False" for each statement. | If the solid sphere is an insulator (instead of metal) with net charge Q, the charges are wherever they were placed, and cannot move around. \/| The electric field near the metal surface on the outside is perpendicular to the surface. If the solid sphere is an insulator (instead of metal) with net charge Q,...
2. Potentials and a Conducting Surface The electric potential outside of a solid spherical conductor of radius R is found to be V(r, 9) = -E, cose (--) where E, is a constant and r and 0 are the spherical radial and polar angle coordinates, respectively. This electric potential is due to the charges on the conductor and charges outside of the conductor 1. Find an expression for the electric field inside the spherical conductor. 2. Find an expression for...
Consider a sphere of radius a with a uniform charge distribution over its volume, and a total charge of q_o. Use Gauss's Law to calculate the electric field outside the sphere, and then inside the sphere. Solve the general problem in r, recognizing that problem spherical symmetry. Draw a graph of the electric field the has the surface of the strength as a function of noting where if the surface of the sphere is (a). Some hints: the surface area...
Could you explain how to solve this clearly and neatly please? This is a cross section of two nested spheres. The outer sphere is a thin conductor of radius M with a uniform charge distribution -o and total charge -Q along its surface. The inner sphere is a solid insulator of radius L. It has a uniform volume charge density of ρ a total charge of +Q. There is a vacuum between them. Region C 1.) (3pts) Determine the electric...
The electric charges are disturbed inside of a sphere. What would happen to the net electric flux through the surface of that sphere when the radius is doubled? Is is a) doubled b) halved c) remain the same or d) does it increased by a factor of four When a conductor is in electro static equilibrium, any axcess charge on a conductor a)cannot be detected B)is on the surface c) is fixed in space d)is evenly distributed or e) is...
Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
