Problem: Four masses lie in a rectangular arrangement in the xy - plane. One mass is at the origin and the rectangular legs are parallel to the CS axes. The x-axis legs are 0.617 m, while the y- axis legs are 0.385m. Beginning at the origin and proceeding clockwise, the masses are 0.350kg, 0.473kg, 0.662kg, and 0.858kg.

Part A: Determine the net gravitational force on each of the masses.

I don't just need an answer, work and explanations/walkthrough would be much appreciated! Thank you.
