Calculating Potential of a Uniformly Charged Dielectric Sphere

Given:
- Charge Q is uniformly distributed throughout the volume of a dielectric sphere of radius R.
- The potential at the surface of the sphere, r = R, is 24 volts.

To Find:
- The potential at r = 3R.
- The potential at r = 2R.

Solution:

  1. Electric Field Inside and Outside the Dielectric Sphere
    For a uniformly charged sphere with volume charge density ρ, the electric field inside and outside the sphere is given by:


    • Inside the sphere (r < r):="" e="" />0)

    • Outside the sphere (r > R): E = (Q/4πε0r2)



  2. Electric Potential Inside and Outside the Dielectric Sphere
    The electric potential at a point P due to a charge Q is given by:


    • V = (1/4πε0) * (Q/r)


    Using this formula, we can find the electric potential inside and outside the sphere:


    • Inside the sphere (r < r):="" v="" />0) * ((ρr2)/6)

    • Outside the sphere (r > R): V = (1/4πε0) * (Q/r)



  3. Dielectric Constant and Electric Field
    For a dielectric material with dielectric constant κ, the electric field inside the material is reduced by a factor of κ:


    • Einside = (Evacuum/κ)



  4. Electric Potential and Dielectric Constant
    The electric potential inside a dielectric material with dielectric constant κ is also reduced by a factor of κ:


    • Vinside = (Vvacuum/κ)



  5. Finding the Potentials at r = 3R and r = 2R
    Using the above formulas and the given values, we can find the potentials at r = 3R and r = 2R:


    • At r = 3R:


      • Inside the sphere (r < r):="" v="" />0) * ((ρ(3R)2)/6κ) = (1/4πε0
