Three charges +5C, +7C 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

10 C

Text Solution

Verified by Experts

The correct Answer is:
C
T.N.E.I. = `q_(1)+q_(2)+q_(3)`
= 5 + 7 - 4 = 8C
T.N.E.I. depends upon charge inside the surface only.
