How Do You Calculate the Gravitational Force on a 2 kg Mass?

[armanio99]

Homework Statement

Three masses are arranged in the (x, y) plane
as shown. What is the magnitude of the resulting
force on the 2 kg mass at the origin? The
value of the universal gravitational constant
is 6.6726 × 10^−11 N · m^2/kg^2 .
Answer in units of N

2kg @ (0,0)
5kg @ (4,2)
6kg @ (1,-3)

Please show step by step.
