Astar is located at < 3×1010, 7×1010, 2×1010 > m. a planet is located at < - 5×1010, - 4×1010, 7×1010 > m. what is the vector pointing from the star to the planet? (in vector form) what is the vector r→ps pointing from the planet to the star?

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    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
