Step 1
The formula is: V = (Q / (4πε₀)) * ((3R² - r²) / (2R³)) where: - V is the electric potential, - Q is the total charge, - ε₀ is the permittivity of free space (approximately 8.85 x 10^-12 C²/N·m²), - R is the radius of the sphere, and - r is the distance from the Show more…

$\stackrel{\text { -e }}{\text { Charge }} Q=+4.00 \mu \mathrm{C}$ is distributed uniformly over the volume of an insulating sphere that has radius $R=5.00 \mathrm{~cm}$. What is the potential difference between the center of the sphere and the surface of the sphere?
A solid conducting sphere of radius $2.00 \mathrm{~cm}$ has a charge $8.00 \mu \mathrm{C}$. A conducting spherical shell of inner radius $4.00 \mathrm{~cm}$ and outer radius $5.00 \mathrm{~cm}$ is concentric with the solid sphere and has a charge $-4.00 \mu \mathrm{C}$. Find the electric field at (a) $r=1.00 \mathrm{~cm}$, (b) $r=3.00 \mathrm{~cm}$, (c) $r=4.50 \mathrm{~cm}$, and (d) $r=7.00 \mathrm{~cm}$ from the center of this charge configuration.
