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

Answer 1

Answer: (C)

$q$ is +ve because lines of force emerge from it and $|Q|<|q|$ because more lines emerge from $q$ and less lines terminate at $Q$.
