Calculate the amount of work that would be required to move a small positive test charge q0q0 slowly from r=2Rr=2R to r=7Rr=7R. Assume that the presence of q0q0 has no effect on how the charge qq is distributed over the sphere.
Express your answer in terms of the electric constant ϵ0ϵ0epsilon_0 and some or all of the variables q, q0, and R.

A sphere of radius R has total charge Q. The volume charge density (C/m3) within the sphere is ρ(r)=C/r2, where C is a constant to be determined. The charge within a small volume dV is dq=ρdV. The integral of ρdV over the entire volume of the sphere is the total charge Q. Use this fact to determine the constant C in terms of Q and R. Hint: Let dV be a spherical shell of radius r and thickness dr. What...
