Look at the following figure showing the electric field lines in the vicinity of two point charges. Which of the following values could represent the charges on A and B? Select one: A is positive, B is positive, and |A| > |B|. A is positive, B is positive, and |A| = |B|. A is positive, B is positive, and |A| < |B|. A is negative, B is negative, and |A| = |B|. A is negative, B is negative, and |A| < |B|.

Step 1
Since the electric field lines are going outwards from A, charge A must be positive. Since the electric field lines are going inwards towards B, charge B must be negative. ** Show more…

Figure below represents the field lines of the electric field created by two equal positive charges. Rank the magnitude of the electric field at the points A, B and C from weakest to strongest.

Figure shows the clectric lines of force cmerging from a charged body. If the electric fields at $A$ and $B$ arc $E_{A}$ and $\mathcal{E}_{B}$. respectively, and if the distance belween $A$ and $B$ is $r$, then a. $E_{A}>E_{B}$ b. $E_{A}<E_{B}$ c. $E_{A}=E_{B} / r$ d. $E_{A}=E_{B} / r^{2}$
In this exercise, you will practice drawing electric field lines. Make sure you represent both the magnitude and direction of the electric field adequately. Note that the number of lines into or out of charges is proportional to the charges. (a) Draw the electric field lines map for two charges $+20 \mu C$ and $-20 \mu C$ situated $5 \mathrm{cm}$ from each other. (b) Draw the electric field lines map for two charges $+20 \mu \mathrm{C}$ and $+20 \mu \mathrm{C}$ situated $5 \mathrm{cm}$ from each other. (c) Draw the electric field lines map for two charges $+20 \mu \mathrm{C}$ and $-30 \mu \mathrm{C}$ situated $5 \mathrm{cm}$ from each other.
