A positively charged particle P is in an electric field, as shown. [Figure 30.1] The field lines (lines of force) are evenly spaced and parallel. Which statement is correct?

This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.

AMoving P a small distance in any direction will not change the electric force on P.

BMoving P a small distance in direction Y will increase the electric force on P.

CMoving P a small distance in direction Z will increase the electric force on P.

DMoving P a small distance in direction X will increase the electric force on P.

✓ Correct answer

A: Moving P a small distance in any direction will not change the electric force on P.
