The electric field lines of a negatively charged particle are-

The electric field lines of a negatively charged particle are- Correct Answer radial and inwards

The correct answer is option 2) i.e. radial and inwards

CONCEPT:

  • Electric field lines: An electric field line is defined as an imaginary curve drawn in such a way that the tangent to it at each point gives the direction of the net electric field at that point. They are the visual representation of the electric field as lines.
  • Properties of Electric Field Lines:
    1. ​​The field lines never intersect. 
    2. The field lines are perpendicular to the surface of the charge.
    3. The magnitude of the electric field is directly proportional to the number of electric field lines.
    4. The electric field line emerges from +ve charge and meets the −ve charge, or starts or ends at infinity if there is only a single charge.

EXPLANATION:

  • The electric field lines emerge from a +ve charge and appear to meet the -ve charge.
  • Hence, for a negatively charged particle, the electric field lines will be radial and directed inwards.
