A non-conducting sphere of radius 5.6 cm has a uniform volume charge with a charge density of rho = 41.4 mu C/m^3. What is the electric field at r = 2.95 cm?
A sphere of radius 1.2 cm has a constant volume charge density of 0.7 μC/m3. What is the magnitude of the electric field in N/C at a radius of 6 cm from the center of the sphere to 2 decimal places?
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...
