Question

The electric flux over the surface of a sphere if it is charged with 10uc is

Answer 1

We know the electric flux over the surface of a sphere is

Ф=E.A

Or, Ф=E.4πr^2

Or, Ф=Q/ε0;

Where, r= Q/4πε0r^2 and ε0 = permittivity of free space=8.854187817...×10−12 F⋅m−1

Given, Q= 10uC= 10×10^-6 C

So Electric field Ф=Q/ε0

Or, Ф={(10×10^-6)/ε0} v.m
