Three charges +5C, +7V and -4C are situated within a closed surface and charges -5C, -7C and +4C are situated outisde the surace what is the T.N.E.I. over the closed surface?

A

`-8C`

B

`0`

C

`+8C`

D

`10C`

Text Solution

Verified by Experts

The correct Answer is:
C
The charges situated outside the surface do not contribute to T.N.E.I. for the internal charges
`sumQ=7+5-4=+8C=T.N.E.I`.
