AP Physics C E&M Practice Questions - AP Physics C Electricity and Magnetism Exam - AP Physics C E&M Practice Questions - AP Physics C Electricity and Magnetism Exam

Question 1

Two point charges of +2.0 microcoulombs and +8.0 microcoulombs are separated by 0.30 m in vacuum. What is the magnitude of the electrostatic force between them? (k = 8.99 x 10^9 N m^2/C^2)

1.6 N 0.16 N 16 N 0.48 N

Correct Answer:

1.6 N

Question 2

A solid conducting sphere carries a net charge Q. Using Gauss's law, what is the electric field at a point inside the conductor (at radius r less than the sphere's radius R) in electrostatic equilibrium?

kQ/r^2 directed radially outward kQ/R^2, constant everywhere inside Zero kQ/r, directed radially inward

Correct Answer:

Zero

Question 3

An infinite line of charge has uniform linear charge density lambda. Using Gauss's law with a cylindrical surface, the electric field at distance r from the line is:

lambda / (2 pi epsilon0 r) lambda / (4 pi epsilon0 r^2) lambda r / (2 epsilon0) lambda / (epsilon0 r^2)

Correct Answer:

lambda / (2 pi epsilon0 r)

Question 4

An infinite plane of charge has uniform surface charge density sigma. The magnitude of the electric field a small distance from the plane is:

sigma / (2 epsilon0) sigma / epsilon0 sigma / (4 pi epsilon0) sigma r / epsilon0

Correct Answer:

sigma / (2 epsilon0)

Question 5

Electric flux through a closed surface is defined by the integral of E dot dA. According to Gauss's law, this total flux equals:

The enclosed charge divided by epsilon0 The product of the field magnitude and the surface area The enclosed charge times epsilon0 Zero for any closed surface

Correct Answer:

The enclosed charge divided by epsilon0
