Problem

5\,\text{kg}

point mass is located at

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

and a

12\,\text{kg}

point mass is located at

(0,\,4\,\text{m})

in the

xy

-plane. Taking the origin at

(0,0)

, what is the magnitude of the net gravitational field at the origin? a)

4.5\times10^{-11}\,\text{N kg}^{-1}

6.2\times10^{-11}\,\text{N kg}^{-1}

2.3\times10^{-10}\,\text{N kg}^{-1}

8.7\times10^{-11}\,\text{N kg}^{-1}
