Which statement is the best for electric flux of a point charge?
- A
Independent of charge
- B
Independent of medium
- C
Independent of shape of surface in which charge is enclosed
- D
Independent position of charge in shape
Electric flux is given as;
Φ =Q/ε0
So, electric flux depends upon medium and charged enclosed. It is independent of shape of surface in which charge is enclosed.
Wrong – flux directly depends on the enclosed charge (Φ∝q).
Wrong – denominator has ε0(or ε in a medium), so flux depends on medium.
Electric flux is given as;
Φ =Q/ε0
So, electric flux depends upon medium and charged enclosed. It is independent of shape of surface in which charge is enclosed.
Wrong → while total flux through the surface stays the same, the flux distribution (field lines density through different parts of the surface) depends on where the charge is inside. That’s why this option is not correct.
