Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,
then the following gives us the potential difference,
the formula
may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get
using q = 8.00 × 10⁻¹⁹ c and δv = 2.00 v, we get
(2.00\text{ v}) \\ & = 1.60\times 10^{-18}\text{ j} \end{aligned})
the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
