Question

The given figure gives electric lines of force due to two charges $q_{1}$ and $q_{2}$ . What are the signs of the two charges?

• A. Both are negative
• B. Both are positive
• C. $q_{1}$ is positive but $q_{2}$ is negative
• D. $q_{1}$ is negative but $q_{2}$ is positive

Answer 1

Answer: (A)

Both are negative

Answer 2

The electric lines of force are directed from higher potential to lower potential. The lines are directed towards $q_{1}$ and $q_{2}$ from neighboring points, so $q_{1}$ and $q_{2}$ both are negative (at lower potential).
