Understanding Electric Field: True Statements & Examples

Click For Summary
SUMMARY

This discussion focuses on the properties of electric fields in the context of charged spheres. Key conclusions include that the electric field inside a conducting sphere is zero, while the field outside behaves as if it originates from a point charge at the center. Additionally, it is established that the electric field between the inner and outer radii of a conducting sphere is always zero, and the distribution of charge on the outer sphere is influenced solely by its own charge, independent of other charges present. The discussion emphasizes the smooth variation of electric fields as one moves away from the origin.

Which of the statements regarding this situation are true? Select all that apply.

1-When one charged sphere is placed inside another the net electric field outside the larger sphere is always larger than the field due to the larger sphere alone.

2-If there is a positive point charge present at the center, the field in all regions is either zero or directed away from the center.

3-When one charged sphere is placed inside another the net electric field outside the larger sphere is always non-zero.

4-It is possible to have no electric field inside the outer sphere and a non-zero electric field outside the outer sphere.

5-If the outer sphere is present the electric field between its inner radius and its outer radius (inside its solid wall, in other words) is always zero.

6-It is not possible to have a non-zero electric field inside the inner sphere and outside the outer sphere, but no electric field between the inner and outer spheres.

7-For a conducting sphere with a net charge Q, the electric field inside the sphere is zero and the electric field outside the sphere is the same as the field from a point charge of charge Q placed at the center of the sphere.

8-As you move steadily out from the origin in this simulation the electric field changes smoothly. The field can never jump suddenly from one value to another.

9-If the outer sphere is present the way charge is distributed on the outer sphere depends only on its charge, and not on the charge of the point charge and the inner sphere.

Welcome to PF. We have a rule here that people wanting help first must show the effort they have put into a problem. That way we don't do your HW for you, and also we will know where to help you best.
