Problem

1\,\text{kg}

mass is placed at the origin of a Cartesian coordinate system. Two other point masses are fixed at positions

(0.40\,\text{m},0)

with mass

4\,\text{kg}

and

(0,0.30\,\text{m})

with mass

3\,\text{kg}

. (Take

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

.) (a) Calculate the magnitude of the gravitational force on the

1\,\text{kg}

mass due to the

4\,\text{kg}

mass. (b) Calculate the magnitude of the gravitational force on the

1\,\text{kg}

mass due to the

3\,\text{kg}

mass. (c) Hence determine the magnitude of the resultant gravitational force on the

1\,\text{kg}

mass and the angle it makes with the positive

x

-axis.
