Question

The intensity of the electric field at a point at a perpendicular distance ‘r’ from an infinite line charge, having linear charge density ‘λ’ is given by:

Options

• E = `(1/(4π∈_0))λ/r`

• E = `(1/(4π∈_0)) (2λ)/r`

• E = `(1/(4π∈_0)) λ/r^2`

• E = `(1/(4π∈_0)) (2λ)/r^2`

Answer 1

E = `(1/(4π∈_0)) (2λ)/r`

The intensity of the electric field at a point at a perpendicular distance ‘r’ from an infinite line charge, having linear charge density ‘λ’ is given by: E = `(1/(4π∈_0)) (2λ)/r`
