MCQ
The direction of electric field created by a negative charge is ___________?
  • A
    Directed outwards.
  • B
    Directed towards the charge.
  • C
    Maybe outwards or towards the charge.
  • D
    Circular in shape.

Answer

  1. Directed towards the charge.

Explanation:

If a unit positive charge is kept near a negative charge, the unit positive charge will be attracted towards the negative charge. That means the electric field is towards the negative charge. But in case of positive charge, the field is directed away from the charge.
