Two conducting spheres with radius r1 and r2 and charges q1 and q2, respectively, are connected with a conducting wire. The one with more charge will have a higher potential. Select one: True O False Check Two conducting spheres with radius r1 and r2 and charges q1 and q2, respectively.

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)...

two charged spherical conductors of radius R1=6cm and R2=2cm are separated by a distance much greater than 6cm and are connected by a long, thin conducting wire. a total charge Q=80nc is placed on one of the spheres. (a) what is the charge on each sphere? (b) what is the electric field near the surface of each sphere? (c) what is the electric potential of each sphere? (assume that the charge on the connecting wire is negligible)

A conducting sphere of radius r1 = 0.45 m has a total charge of Q = 1.1 μC. A separate uncharged conducting sphere of radius r2 = 0.21 m connects to the first by a slim conducting wire. The spheres are separated by a huge distance compared to their size . Part (b) What is the surface charge density of the second sphere, σ2, after they are connected in coulombs per square meter?

A conducting sphere of radius r1 = 0.26 m has a total charge of Q = 1.1 μC. A second uncharged conducting sphere of radius r2 = 0.45 m is then connected to the first by a thin conducting wire. The spheres are separated by a very large distance compared to their size. What is the total charge on sphere two, Q2 in coulombs?
Sphere 1 with radius R1 has positive charge q. Sphere 2 with radius
Sphere 1 with radius R1 has positive charge q. Sphere 2 with radius 7.0R1 is far from sphere 1 and initially uncharged. After the separated spheres are connected witha wire thin enough to retain only negligible charge, what fraction of q ends up on (a) sphere 1 and (b) sphere 2? (c) What is the ratio of the final surface chargedensity of sphere 1 to that of sphere 2? (Answer with 2 significant figures.)

A small, solid conducting sphere of radius r1 sits inside a hollow conducting spherical shell of inner radius r2 and outer radius r3. A potential difference of magnitude V is placed across the inner and outer conductors so that there is a net charge of -Q on the inner conductor and +Q on the outer conductor. Suppose a thin but finite thickness conducting shell was placed between the sphere and the outer shell. This extra shell is electrically isolated. Would...
