SUMMARY
The electric field E at a distance d from a point charge can be expressed using the formula E = (k)(q/d²). To determine the distance at which the electric field's magnitude becomes 2E, the correct calculation leads to the conclusion that this distance is d/sqrt(2). This conclusion is confirmed by multiple participants in the discussion, validating the use of the formula and the derived distance.
