In a region, the intensity of an electric field is given by `vecE = 2hati + 3hatj + hatk` in . `NC^(-1)` The electric flux through a surface `vecS =10hati m^2` in the region is

A

`5 Nm^(2) C^(-1)`

B

`10 Nm^(2) C^(-1)`

C

`15 Nm^(2) C^(-1)`

D

`20 Nm^(2) C^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
D
`phi = vecE. vecS = (2hati + 3hatj + hatk) . (10 hatj) = 20 Nm^2//C`
