Question

Find the electric potential energy of a unifomly charged then spherical shell.

Answer 1

Answer:

The electric potential energy of a uniform charged.

Radius=r

Charge=q

Electric potential

E= 1/2(1/4π epsilon0*q^2/r)

= 1/8K q^2/r

Answer 2

TO FIND :

Electric potential energy of a uniformly charged thin spherical shell.

SOLUTION :

◆Potential of a uniformly charged thin spherical shell,

V = q /( 4πƐR)

Where, R - radius of shell,

Ɛ - permittivity of the medium.

◆For potential energy;

Integrate potential along the charges gives potential energy.

◆ANSWER :

Potential Energy, U = ∫q / (4πƐR). (from 0 to q)

= q^2/ (2× 4πƐR)

= q^2/ (8πƐR).
