Problem

Three masses are arranged in a rectangle. Mass

m_{1} = 3\,\text{kg}

is at

(0, 4)

, mass

m_{2} = 4\,\text{kg}

is at

(3, 0)

, and mass

m_{3} = 5\,\text{kg}

is at

(0, 0)

. (Coordinates in meters). Calculate the magnitude of the net gravitational force experienced by the mass

m_{3}

at the origin.
