Continuous Charge Distributions

What is a key characteristic of a continuous charge distribution?

• It is a charge concentrated at a single point.

• It is a charge that has a specific shape and is continuously distributed throughout the object.

• It is a charge that is uniformly distributed on a surface only.

• It is a charge that is discrete and countable.

Which equation represents the electric field caused by a point charge?

• E = F_e / q

• F_e = k * (q1 * q2) / r^2 * r_hat

• E = k * Q / r^2 * r_hat

• E = integral(k * dq / r^2 * r_hat)

How is the electric field caused by a continuous charge distribution typically determined?

• By directly applying Coulomb's Law to the entire object.

• By treating the object as a single large point charge.

• By summing the electric fields from an infinite number of infinitesimally small point charges using integration.

• By measuring the force on a test charge at various points.

What are the standard SI units for surface charge density?

• Coulombs per meter (C/m)

• Coulombs per meter squared (C/m^2)

• Coulombs per meter cubed (C/m^3)

• Newtons per Coulomb (N/C)
