Question

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

(A) EA>EB (B) EA < EB (C) EA=(EB/r) (D) EA=(EB/r2)

In a strong electric field, field lines are crowded, and in a weak field, lines are sparse. From the figure, we can say that the field at A is stronger than the field at B . ∴ EA>EB .

Q. The 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. If the distance between $A$ and $B$ is $r$ , then

$E_{A} > E_{B}$

$E_{A} < E_{B}$

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

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