Electric Flux

Question

Figure shows the electric lines of force emerging from a charged body. If the electric field at A and B are $E_{A} a n d E_{B}$ respectively and if the displacement between A and B is then

Easy

A

$E_{A} > E_{B}$
B

$E_{A} < E_{B}$
C

$E_{A} = \frac{E_{B}}{r}$
D

$E_{A} = \frac{E_{B}}{r^{2}}$

Solution

$E_{A} > E_{B}$
As strength of the electric field is proportional to no of lines of force per unit area.
