Calculation of Potential Difference between Two Concentric Uniformly Charged Spheres


Given Information


  • Radius of the inner sphere = 10 cm

  • Radius of the outer sphere = 20 cm



Assumptions


  • The charge on both spheres is uniformly distributed.

  • The charge on both spheres is spherically symmetric.



Calculation of Potential Difference


The potential difference between two concentric uniformly charged spheres can be calculated using the following formula:


V = k( Q1 / r1 - Q2 / r2 )


Where,


  • V = Potential difference between the two spheres

  • k = Coulomb's constant = 9 x 10^9 Nm^2/C^2

  • Q1 = Charge on the inner sphere

  • r1 = Radius of the inner sphere

  • Q2 = Charge on the outer sphere

  • r2 = Radius of the outer sphere



Since the spheres are uniformly charged, we can calculate the charge on each sphere as:


Q = 4πεr^2σ


Where,


  • Q = Charge on the sphere

  • ε = Permittivity of free space = 8.85 x 10^-12 C^2/Nm^2

  • r = Radius of the sphere

  • σ = Surface charge density



Since the charge is uniformly distributed, we can calculate the surface charge density as:


σ = Q / (4πr^2)


Using the above formulas, we can calculate the charge on each sphere:



  • Charge on the inner sphere (Q1) = 4πεr1^2σ

  • Charge on the outer sphere (Q2) = 4πεr2^2σ



Substituting the above values in the formula for potential difference, we get:


V = k( Q1 / r1 - Q2 / r2 )


V = 9 x 10^9 ( (4πεr1^2σ) / r1 - (4πεr2^2σ) / r2 )


V = 9 x 10^9 ( 4πεσ / r1 - 4πεσ / r2 ) (r1^2r2^2 / r1r2)


V = 36πεσ (r2^2 - r1^2) / r1r2


Substituting the values of ε, σ, r1, and r2, we get:


V = 36π(8.85 x 10^-12)( (1 / 0.1) - (1 / 0.2) ) / 0.1 x 0.2


V =
