Three point masses 'm' each are placed at the three vertices of an equilateral traingle of side 'a'. Find net gravitational force on any point mass.

Three equal masses of 1 kg each are placed at the vertices of an equilateral triangle of side 1 m, then the gravitational force on one of the masses due to other masses is (approx.)
