• Contour lines joins up points on a surface that are of the same height.
  • Field lines points towards the direction of the steepest descent.

As you may have noticed, whenever a field line and contour line crosses each other, they are perpendicular.

Prove it.

    Hint

    Line of greatest descent is the shortest distance between two contour lines.


    I’m sure there are many other ways to solve this, as it is a very open ended question. But anyways this is one of the favourite proof i’ve done
