The electric field in a region is given ...

The electric field in a region is given by `E = 3/5 E_0hati +4/5E_0j` with `E_0 = 2.0 × 10^3 N//C`. Find the flux of this field through a rectangular surface of area `0.2 m^2` parallel to the y-z plane.

Text Solution

Verified by Experts

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