일반물리학 1 — Gravitation: Problem 17

17 The Sun’s center is at one focus of Earth’s orbit. How far from this focus is the other focus, (a) in meters and (b) in terms of the solar radius, \(6.96 \times 10^8 \text{ m}\)? The eccentricity is 0.0167, and the semimajor axis is \(1.50 \times 10^{11} \text{ m}\).
