Charge q = 4.00 μc is distributed uniformly over the volume of an insulating sphere that has radius r = 12.0 cm . a small sphere with charge q=+ 2.00 μc and mass 6.00×10−5kg is projected toward the center of the large sphere from an initial large distance. the large sphere is held at a fixed position and the small sphere can be treated as a point charge.

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.
