Figure shows the electric lines of force emerging from a charged body. The electric field at A and B are EA and En, respectively. If the distance between A and B is r, then

• A

  ${\mathrm{E}}_{\mathrm{A}}>{\mathrm{E}}_{\mathrm{B}}$

• B

  ${\mathrm{E}}_{\mathrm{A}}<{\mathrm{E}}_{\mathrm{B}}$

• C

  ${\mathrm{E}}_{\mathrm{A}}=\frac{{\mathrm{E}}_{\mathrm{B}}}{\mathrm{r}}$

• D

  ${\mathrm{E}}_{\mathrm{A}}=\frac{{\mathrm{E}}_{\mathrm{B}}}{{\mathrm{r}}^2}$
