Question

Part D: What is the electric field Eext outside the conductor a. Zerg b. The same as the field produced by a point charge q located at the center of the Constants Figure 1)A spherical cavity is hollowed out of the interiorsnher of a neutral conducting sphere. At the center of the cavity is a point charge, of positive charge q c. The same as the field produced by a charge located at the position of the charge in the cavity now a second charge, q2, is brought near the outside of the conductor. Which of the following quantities would change?** Figure ) ** Part E: The total surface charge on the wall of the cavity, gint: a.Change b. Would not change Part F: The total surface charge on the exterior of the conductor, gext: a. Would change b. Would not change Part G: The electric field within the cavity, Ecav a. Would change b. Would not change Part H: The electric field outside the conductor, Eext a. Would change b. Would not change

Explanation / Answer

D) b) will be correct as electric field due to conducting sphere will be zero as net charge in sphere =0 and in inside charge it will distribute - q, charge such that E due to +q charge and charge in cavity wall-q =0

E)b) wouod not change

F) b) would not change

As net charge inside conductor =0 and net charge on conductor=0 these constraints hold

G) b) as conductor does not allows other charge electric field to pass inside it

H) a) as there is an extra charge - q
