Physical processes are sometimes described visually by lines. Only the following can cross -

Options

  1. AStreamlines in fluid flow
  2. BLines of forces in electrostatics
  3. CRays in geometrical optics
  4. DLines of force in magnetism

Correct answer

C. Rays in geometrical optics

Step-by-step solution

A If stream lines intersect then there will be two direction of fluid flow at a point, which is absurd. B Lines of forces in electrostatic never intersect D Line of force in magnetism never intersect each other.
