A particle of mass $m$ moves in a circular path of radius $R$ under the influence of a central force $F(r) = -kr^n$, where $k > 0$ and $n$ is a real number. If the particle is in a stable circular orbit at a radius $r_0$, which of the following conditions must be met for $n$?
A point charge +q is placed at the origin. A Gaussian surface in the shape of a sphere of radius R is centered at the origin. If the charge is moved to a point (R/2, 0, 0) within the sphere, what happens to the electric flux through the Gaussian surface?
Consider a long, straight, uniformly charged wire with linear charge density $\lambda$. A cylindrical Gaussian surface of radius r and length L is coaxial with the wire. If the wire is replaced by a thin cylindrical shell of radius R (where R < r) carrying the same linear charge density $\lambda$, what is the electric field at a radial distance r from the axis of the shell?
