Question

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. $E_A=\frac{E_B}{r^2}$
• D. $E_A=\frac{E_B}{r}$

Answer 1

The correct option is B $E_A>E_B$


Case of non-uniform field:
In a non-uniform electric field, the intensity of the electric field is directly proportional to its density.
Since electric field lines are denser at point A than point B, therefore $E_A>E_B$
