22N.2.HL.TZ0.a

The diagram shows field lines for an electrostatic field. X and Y are two points on the same field line.

Outline which of the two points has the larger electric potential.

[2]

Markscheme

potential greater at Y ✓

 

«from E=-ΔVeΔr» the potential increases in the direction opposite to field strength «so from X to Y»

OR

opposite to the direction of the field lines, «so from X to Y»

OR

«from W=q∆Ve» work done to move a positive charge from X to Y is positive «so the potential increases from X to Y» ✓

Examiners report

A significant majority guessed at X, probably because the field lines are closer together. Those that identified Y were generally successful in their explanation.
