The electric field in a region is given ...

The electric field in a region is given by `vecE=3/5 E_0veci+4/5E_0vecj` with `E_0=2.0 xx 10^3 N C^(-1)`. Find the flux of this field through a recatngular surface of area `0.2m^2` parallel to the y-z plane.

Text Solution

Verified by Experts

`phi_(E) = vec(E).vec(S) = ((3)/(5)E_(0)vec(i) + (4)/(5)E_(0)vec(j)).(0.2 hat(i)) = 240(N-m^(2))/(C )`
