## What is the equation for the electric field of a long straight wire?

The electric field due to an infinite line charge with a uniform distribution is given by the equation: E=λ2πϵ0r E = λ 2 π ϵ 0 r , where: λ is the linear charge density.

## What is the magnitude of a point charge due to which the electric field 30 cm?

The magnitude of point charge due to which the electric field 30 cm away has the magnitude 2 NC1 will be 2 x 1011 C.

## What is the electric field of a long wire?

The electric field is a vector quantity and it is denoted by E. the standard units of the electric field is N/C. Consider an infinitely long wire with linear charge density λ and length L. To calculate electric filed, we assume a cylindrical Gaussian surface due to the symmetry of wire.

## What is e V l?

The magnitude of electric field strength is E=V/ℓ.
