Electric Field Lines

Practice Questions:

Question 1: easy

Find out correct relation between electric field intensity EA & EB present at two points in an electric field shown in the figure.

1. \[ E_{A}=E_{B}\]

2. \[ E_{A}>E_{B}\]

3. \[ E_{A}< E_{B}\]

4. Data insufficient

View Answer

Distance between electric field lines represents magnitude of electric field lines. Large is the separation between electric field line lesser is electric field. so ,

\[ E_{A}< E_{B}\]

Question 2: easy

Which of the following configurations of electric lines of force is not possible ?

4. both (2) and (3)

View Answer

Option 2 is wrong because electric field lines emerge out of +ve charge and submerge into -ve charge.

In option 3 number of electric field lines is proportional to amount of charge. From +5C charge 6 field lines are emerging out where as from 1C charge only one electric field line is present.
