The electric field ( E in NC ⁻¹ ) in a region is given by E =3 i +5 i . The net electric flux through a square area of side 2 ~m parallel to y - z plane is
Options
- A3 NC ⁻¹ ~m ^2
- B6 NC ⁻¹ ~m ^2
- C12 NC ⁻¹ ~m ^2
- D24 NC ⁻¹ ~m ^2
Correct answer
B. 6 NC ⁻¹ ~m ^2
Step-by-step solution
The net electric flux through a square area A=2 2=4 ~m ^2 parallel to y-z plane only, as or.ly i component will cause any flux Flux = E A =3 4=12 ~N C ⁻¹ ~m ^2 .
