Question

A conducting sphere of radius 5 cm has a charge of 31-41 C Calculate the
surface density of charge.​

Answer 1

Answer:

given = radius = 5cm

           charge = 31.41C

to find = surface charge density (σ)

solution =  surface density for charge =

                  σ = charge / area

we know the area of sphere is 4Πr²

                  σ =  31.41 /  4 X  Π X 5 X 5

                  σ  =   31.41 / 314

                  σ =   0. 10003μ Coul/m²

surface density of charge.​  σ =   0. 10003μ Coul/m²
