- Homework Statement
- Two planets with mass M1 and M2 revolve around each other in circular orbits. The distance between them is r. A mass m that is located on the surface of M1 with radius R feels fictitious force that modifies the mass's acceleration. Assume that mass m is very small and ignore the effect from M1's rotation. (see figure)

Write down the vector of the fictitious force in m, M2, r, gravity constant G, and unit vector!

I have a difficulty in understanding the question.

Fictitious force is a force whose motion is described using a non-inertial frame of reference. Which frame is the question referring to?
