Figure shows the e 1 e c tr ic lines of f o rce s emerging from a charged body. If the electric field at $A$ and $B$ are $E_A$ and $E_B$ respectively and if the displacement between $A$ and $B$ is $r$, then Figure

  • Correct answer
    A
    $E_A>E_B$
  • B
    $E_A < E_B$
  • C
    $E_A=E_B / r$
  • D
    $E_A=E_B / r^2$.

Solution

Since the density of the electric lines of force at $A$ is more than that at $B$, the electric field at $A, E_A>E_B$ (elecric field at $B$ ).

Hence, the correct answer is option: 'A'.
