    Volts/Meter

    Newtons/Coulomb

    Explanation:

    Volts / Meter and Newtons/Coulomb both are same and the units of Electric field intensity or electric field strength.

    Electric field strength E is the force per unit charge. It is measured in Newton/Coulomb in SI unit. It is a vector quantity directed in the direction of force.

    Mathematically,

    Electric field strength = Force/Charge

    E = F / q₀

    = Newton / Coulomb = NC⁻¹ 1

    We know that

    Newton = Joule/meter 2

    Also

    Volt = Joule/Coulomb 3

    So put 3 in 2 we get

    Newton = (Volt Coulomb) / meter put in 1

    E = (Volt Coulomb) / (meter Coulomb)

    = Volt / meter

    Hence

    Newton / Coulomb = Volt / meter
