Asked in MDCAT Test Series — Electrostatics, Work and EnergyModerate

Electric field lines:

Correct answer: A. Never cross each other

  • A. Never cross each other
  • B. Can cross each other
  • C. Depends on the shape of charge
  • D. Not enough information is available

Explanation

Electric lines of force never intersect each other because at the point of intersection, two tangents can be drawn to the two lines of force. This means two direction of electric field at the point of intersection, which is not possible

About Electric Field

An electric field is the force experienced per unit positive test charge, with the field of a point charge given by E = kQ/r² and directed away from positive charges or toward negative charges. Questions involve field lines, superposition and force on a charge, while electric field must be distinguished from electric potential.
