Answer:
The electric flux around the soap bubble will be
Ф = q/ε
Explanation:
The radius of the soap bubble = R
The electric field around the soap bubble = E
The electric flux = ?
The soap can be approximated to be a sphere, so we find the surface area of the sphere
For the soap bubble, the surface area will be
A = [tex]4\pi R^{2}[/tex]
Recall that electric flux is given as
Ф = EA
substituting value of A from above, we'll have
Ф = E[tex]4\pi R^{2}[/tex]..... equ 1
Also recall that the electric field E is given as
E = q/(4πε[tex]R^{2}[/tex])
substitute the value of E into equ 1, to get
Ф = q/(4πε[tex]R^{2}[/tex]) * [tex]4\pi R^{2}[/tex]
The electric flux around the soap bubble reduces to
Ф = q/ε
