Pоtentiаl due tо pоint-chаrges: A -7.0-μC point chаrge has a positively charged object in an elliptical orbit around it. If the mass of the positively charged object is 1.0 kg and the distance varies from 5.0 mm to 20.0 mm between the charges, what is the maximum electric potential difference through which the positive object moves? (k = 1/4πε0 = 8.99 × 109 N ∙ m2/C2)
