$M_E=5\mathrm{.}98{10}^{24}kg,R_E=6\mathrm{.}37{10}^{6}m,G=6\mathrm{.}67{10}^{-11}N*\frac{m^2}{k}{g}^2$

Three masses are located at points in the $xy$ plane as follows:

$M_1$ is $2\mathrm{.}50$ kg located at $(2\mathrm{.}0,2\mathrm{.}0)m$

$M_2$ is $3\mathrm{.}50$ kg located at $(0,5\mathrm{.}0)m$

$M_3$ is $5\mathrm{.}50$ kg located at $(-2\mathrm{.}0,-2\mathrm{.}0)m$

What is the magnitude and direction of the net force acting on $M_2$ due to the other two masses?
