You have three charged particles that are initially very far apart from one another, and you must bring then together to form an equilateral triangle of side length, l. particles a and b each carry a charge -q, and particle c carries a charge 4q. how much work must you do to form the triangle? how much work must you do to rearrange the particles so that they are in a straight line with particle c in the center and a distance l between adjacent particles?

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.
