The electric field in a region is given ...

The electric field in a region is given by `bar(E)=abar(i)+bbar(j)`. Here a and b are constants. Find the net flux pasing through a square area of side L parallel to y-z plane.

Text Solution

Verified by Experts

Electric field, `bar(E)=a bar(i)+b bar(j)`
Flux passing through square area, `phi=bar(E).bar(A)=(a bar(i)+b bar(j)).(L^(2) bar(i))=aL^(2) Wb`
