Figure shows the electric lines of force 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

A

${E_A} > {E_B}$

B

${E_A} < {E_B}$

C

${E_A} = \frac{{{E_B}}}{r}$

D

${E_A} = \frac{{{E_B}}}{{{r^2}}}$
