Question

A-How does the electric field vary as one moves away from a point charge? –the outside of a

spherical distribution of charge? -- the inside hollow space of a spherical distribution of charge?

–a line of charge? -- far away from a dipole along the perpendicular bisector? -- an infinite

sheet of charge? -- inside a capacitor?

B-Describe electric field lines from a sphere? –from a flat surface? -- from a pointed object?

C- What is the geometric relationship between electric field lines and equipotentials?

D- How does the voltage vary as one moves away from a point charge? –the outside of a spherical

distribution of charge? -- the inside hollow space of a spherical distribution of charge? –a line of

charge? -- far away from a dipole along the perpendicular bisector? -- an infinite sheet of

charge? -- inside a capacitor?

E-What is a dielectric? How does the electric field change when one is present?

F- How does one charge by induction?

G- Why do both a positively charged rod and a negatively charged rod both attract bits of paper or

Styrofoam?

Answer 1

a)

depends on
the distance between the positive charge and the electron
the charge on the electron
the charge of the positive charge
