Question
For a point charge q that is negative, in what direction is the electric field (E) around it?
Correct Answer
Option B is the correct answer.
Detailed Explanation
Page 4 states: 'For q negative, E is negative and E is directed radially inward.' This is because a positive test charge, by definition, would be attracted to a negative source charge, hence the field points inward.
Hint
Remember the convention for the direction of the electric field: it's the direction of the force a positive test charge would experience.
