During a lightning storm, the bottom of a cloud gains a strong negative electric charge.
If you were to measure the charge at the top of a tall metal pole directly under the
cloud, what would you expect to observe?
A The top of the pole would have no charge
B. The top of the pole would have a positive charge
C
of the pole would have a negative charge
D. The charge of the pole would not be affected by the charge of the cloud.
The top

It should be d if not then c

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.
