SUMMARY
The electric field E generated by a point charge Q at a distance R is described by the formula E = (k)(Q/R²). When the charge is doubled to 2Q and the distance is increased to 2R, the new electric field can be calculated using the same formula. Substituting the new values results in E' = (k)(2Q/(2R)²) = (k)(2Q/4R²) = (1/2)(k)(Q/R²) = E/2. Therefore, the new electric field is E/2.
