Potential due to point-charges: A -7.0-μC point charge 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)

The electric potential difference is calculated using the formula ΔV = k * q * (1/r1 - 1/r2). Substituting the given values: ΔV = 8.99 × 10^9 * 7.0 × 10^-6 * (1/0.005 - 1/0.020) = 9.4 MV.
