In a uniform field along x, the equipotential surfaces are planes:
ATilted at 45 degrees
BNormal to the x axis
CParallel to the x axis
DThrough the origin
Answer & Solution
Correct answer: B. Normal to the x axis
1. The field points along x.
2. Equipotentials are normal to the field.
3. So they are planes normal to the x axis.
