Unit of line integration of electric field is ......

A

`Vm^(-1)`

B

`JC^(-1)`

C

`NC^(-1)`

D

Vm

Text Solution

Verified by Experts

The correct Answer is:
A, C
Integration of electric field
`=int_(P)^(Q)vecE.dvecl`
`= int_(P)^(Q)(vecF.dvecl)/(Q)[because vecE= (vecF)/(Q)]`
`= int_(P)^(Q) (W)/(Q) [ because vecF . d vecl` = W Work]
Unit `=(1)/(C)`
