The Roche limit around a planet is defined as the
A) distance beyond which the orbital velocity of a body in a Keplerian orbit is greater than the escape velocity and matter is no longer captured by the planet.
B) distance inside which a solid satellite (e.g. ,a fragment of rock)will be pulled apart by tidal forces.
C) outer extent of the magnetic field of the planet,or the magnetospheric boundary.
D) distance inside which relative tidal forces will overcome the mutual gravitational forces of a group of particles.
