Question

Which of the following is true for the figure showing electric lines of force? ($E$ is electrical field, $V$ is potential)

• A. $E_A>E_B$
• B. $E_B>E_A$
• C. $V_A>V_B$
• D. $V_B>V_A$

Answer 1

Answer: (A), (D)

$E_A>E_B$
$V_B>V_A$

As the denser field lines give the higher electric field, so the electric filed at A is greater than the electric field at B.
As $E=-\frac{dV}{dx}$ so the potential at B is greater than the potential at A.
Ans: (A),(D)
