Homework Statement
As a moon follows it's orbit around a planet, the maximum gravitational force exerted on the moon by the planet exceeds the minimum gravitational force by 11%. Find the ratio rmax / rmin, where rmax is the moon's maximum distance from the center of the planet and rmin is the minimum distance.
Homework Equations
Newton's law of Gravitation F = G m1m2 / r2
The Attempt at a Solution
I found the ratio to be, rmax / rmin = 0.949 to 3 significant digits.
My textbook says the ratio is 1.05. I think the text if wrong. Can someone try this problem and let me know what you get.
Thanks,
R.
