Sample AP Physics C: Mechanics practice question
An astronomer calculates the mass M of a star based on the period T and orbital radius R of a planet in a circular orbit. Which expression represents the correct application of Newton's laws to determine M?
M = (4π²R³) / (GT²), derived by equating gravitational force to centripetal force
M = (GT²) / (4π²R³), derived by equating gravitational force to centripetal force
M = (4π²R²) / (GT²), derived by equating gravitational force to centripetal force
M = (2πR³) / (GT), derived by equating gravitational force to centripetal force
Explanation
Setting Newton's law of gravitation (GMm/R²) equal to the centripetal force equation (m(2πR/T)²/R) and solving for M yields this expression.
