Direction of field intensity .?

Click For Summary
SUMMARY

The discussion centers on the concept of electric field intensity and its directional implications at a specific point on a 200 Volt equipotential line. Participants clarify that "electric field intensity" is a misnomer, as it refers to the magnitude of the electric field, which is inherently a scalar quantity. The correct interpretation involves identifying the electric field vector's direction, which is perpendicular to the equipotential lines. The consensus is that the question's wording is misleading and should focus on the electric field vector rather than intensity.

Direction of field intensity...?

Problem:
"The vector that best describes the direction of the electric field intensity at point x on the 200Volt equipotential line is"?... ...(five multiple choice options)

There is a diagram of decreasing/increasing equipotentail lines with a point "x" on one which from four vectors are going, two parallel to the line and two perpendicular.

I know the answer they want, so I think I know what they mean( what direction is the electric field vector in).
My question is with the wording, "direction of the electric field intensity".
Does this even make any sense?
From what I understand "electric field intensity" is the magnitude of the electric field at that point. So it is just a scaler and does not have a direction...
Or am I missing/misunderstanding something?

The term "electric field intensity" does not make sense in this context. The vector that best describes the direction of the electric field at point x is the one that you need to select from the multiple choice options.
