WebYes, double the charge means double the change in energy given by the field. And since the work-energy theorem deals with changes in energy, you can easily answer the next question if you know that the initial kinetic energy is zero. since PE + KE = 0, KE = -PE = -2000eV—but actually, none of the answer options have a negative value, and ...
