the high voltage terminal of a rander graaf generator consists of a sphere of radius 0.20m. calculate maximum potential to which it can be raised in air for which the break down potential is 3.0×10^6volt per meter. the charge stored on the sphere in this condition. and the energy stored on the sphere.​

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.
