Statement A is false. Electrostatic field lines do not form closed loops because electrostatic fields are conservative. Statement B is true. Field lines due to a positive point charge are directed radially outward. Statement C is true in the context of the inverse-square electrostatic force law from which the usual spherical-flux result follows. Statement D is true. For a static electric field, ∮E⃗·dl⃗ = 0, so work done around a closed path is zero. Statement E is true. Coulomb force is a centr…
