Three objects A, B and C are moving through space at right angles to each other. The mass of A is 3kg and the mass of B is 8kg. The distance between C and A is r and the distance betwwen C and B is 2r. Fca is 35N 6.2calculate the force between C and B​

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.
