Question

Calculate the electric flux (in units Nm2/C) through an area A= 24 i + 3.2 j m2 in measured in an electric field given by E= 5i+3j N/C?

Answer 1

Given

Area is $A=24 i+3.2 j$

Electric field is $E=5i+3j$

The electric flux through the area is

$\Phi=E.A=(5i+3j).(24i+3.2j)$

$=129.6 N.m^2/C=130 N.m^2/C$
