Choose true or false for each statement. Near a positive charge, the electric field forms circular paths near that charge. B If the magnitude of charge 1 is larger than charge 2, then the density of electric field lines near charge 1 is smaller than near charge 2. Near a positive charge, the electric field points toward that charge.
