The unit of physical quantity obtained by the line integral of electric field is

Options

A. `NC^(-1)`
B. `Vm^(-1)`
C. `JC^(-1)`
D. `C^(2)N^(-1)m^(-2)`

Answer

C

Explanation

The unit of physical quantity obstained by the line integral of electric field is `JC^(-1)`.
i.e. `intEdl=("newton")/("coulomb")xx"length"`
`=("joule")/("coulomb")=JC^(-1)`
