An electric is expressed as `vecE=20 hatiV.m^(-1)`. Find the electric flux passing through a surface of area `0.25m^(2)` normal to the x-axis.

Text Solution

Verified by Experts

The y-z plane is perpendicular to the x-axis.
So the given area vector `vecS=0.25hatim^(2)`
`:.` The electric flux across this area
`pgi=vecE.vecS=(20hati)0.025hati=5V.m`
