As shown above, sphere 1 and sphere 2 are made of metal and connected together by a wire with a switch. While the switch is open, sphere 1 is given a positive total charge (and sphere 2 remains neutral). Then the switch is closed. How does the electric field E1 at the surface of sphere 1 compare to the electric field E2 at the surface of sphere 2?

A metallic solid sphere of radius R is given the charge Q. Which of the followingstatement is true then(a) Electric field at points 0< r < R is zero(b) Charge Q is on the outer surface of the sphere(c) Electric field at r>R is given by Q/4πε0r2(d) Electric field is perpendicular to the surface of the sphere

A metallic sphere, with a radius of 10 cm, has an electric field strength of 3600 N/C on its surface. Another metallic sphere, with a radius of a 5 cm, has the same electric field strength on its surface. These two spheres are connected by a long, thin, metal wire. What is the electric field strength on the surface of the larger sphere after two spheres are connected?

If charges are given to a conducting sphere, then charges goes to :Inner surfaceOuter surface Both None

A positively charged sphere A is brought close without touching a neutral sphere B. Sphere B is touched with a grounded wire. What is the charge on sphere B after the wire is removed?*1 pointpositivenegativeneutralIt depends on the contact time.

A solid conducting sphere of radius R1 = 1.790 m𝑅1 = 1.790 m has a charge of Q = 6.749 μC distributed evenly on its surface. A second solid conducting sphere of radius R2 = 0.6425 m𝑅2 = 0.6425 m is initially uncharged. The second sphere is located a distance of 10 m from the first sphere. The two spheres are momentarily connected with a wire and then the wire is disconnected. What is the charge on the second sphere? (You may enter your calculation using scientific notation.)  C
