Calculate the Roche limit of Moon A around Planet A
in units of meters. The radius of Planet A is
4.2 x 107 m. The density of Planet A is 1400
kg
. The density of Moon A is 2300
The Roche limit is given by the following equation:
Roche limit = RM (2 PM)
where RM is the radius of the planet, PM is the
density of the planet, and Pm is the density of the
moon.
