Question

The lines of force of the electric field due to two charges $q$ and $Q$ are sketched in the figure. State if

• A. $q$ is negative and $|Q|<|q|$
• B. $Q$ is positive and $|Q|>|q|$
• C. $Q$ is negative and $|Q|>|q|$
• D. $q$ is positive and $|Q|<|q|$

Answer 1

The correct option is D $q$ is positive and $|Q|<|q|$

• $q$ is $+ve$ because electric field lines are emerging from it.
• $Q$ is $-ve$ because electric field lines are terminating on it.
• $|Q|<|q|$ because more number of lines emerge from $q$
• Hence, option (c) is correct.
