Two point masses, each of

5\,\text{kg}

, occupy two vertices of an equilateral triangle of side

2\,\text{m}

. Find the magnitude of the net gravitational force on a

1\,\text{kg}

mass placed at the third vertex. (

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

) (a)

2.9\times10^{-10}\,\text{N}

(b)

1.4\times10^{-10}\,\text{N}

(c)

8.3\times10^{-11}\,\text{N}

(d)

1.18\times10^{-10}\,\text{N}
