Question

write electric field in vector form​

Answer 1

Explanation:

The formula for the electric field includes the Coulomb constant, which is . The Coulomb constant can also be written in terms of the permittivity of free space, . In that form, the Coulomb constant is . The unit of the electric field magnitude is Newtons per Coulomb, N/C. = electric field vector at a certain position in space (N/C) k = Coulomb constant ()

mark my answer brainlist ☺

Answer 2

Explanation:

The electric field is a vector quantity, and the direction of the field lines depends on the sign of the source charge. Electric field vectors point away from positively charged sources, and toward negatively charged sources. The formula for the electric field includes the Coulomb constant, which is .
