Q1 · Gauss's Law · EASY
A conducting sphere of radius R carries a charge Q uniformly distributed over its surface. What is the electric field at a distance r from the center of the sphere where r < R?
Q2 · Gauss's Law · EASY
A spherical Gaussian surface of radius R encloses a point charge Q at its center. If the radius of the Gaussian surface is doubled, what happens to the electric flux through the surface?
Q3 · Gauss's Law · EASY
A conducting sphere of radius R carries a charge Q. What is the electric field at a distance r from the center of the sphere where r < R?
Q4 · Gauss's Law · EASY
A conducting sphere of radius R carries a charge Q uniformly distributed on its surface. Using Gauss's law, the electric field at a distance r from the center where r < R is:
