Problem

Two identical masses

M = 5.0\,\text{kg}

are fixed at points

(0,\,a)

and

(a,\,0)

on a Cartesian plane, where

a = 0.20\,\text{m}

. A third mass

m = 0.10\,\text{kg}

is placed at the origin

(0,\,0)

. Calculate the magnitude of the net gravitational force acting on the mass

m

. Use

G = 6.67\times10^{-11}\,\text{N}\,\text{m}^2\,\text{kg}^{-2}
