HOW DO YOU CHOOSE DIRECTION OF ELECTRIC FIELD FOR A POINT X.

Physics

ScanSolve AI Answer

To choose the direction of the electric field at a point X, imagine placing a tiny, positive test charge at that point. The direction of the electric field at point X is the same as the direction of the electrostatic force that would be exerted on that positive test charge.

  • If the source charge creating the field is positive, the electric field at point X will point away from the source charge.
  • If the source charge creating the field is negative, the electric field at point X will point towards the source charge.
