Question
Which of the following is true for the figure showing electric lines of force ? (E is electrical field, V is potential)
Options
A.EA > EB
B.EB > EA
C.VA > VB
D.VB > VA
Solution
A point A the field line are much closer than B hence EA > EB.
Work done by external force in direction of field lines is negative, hence VB > VA.
Work done by external force in direction of field lines is negative, hence VB > VA.
