Three equal masses of \(m\) kg each are fixed at the vertices of an equilateral triangle \(ABC.\) What is the force acting on a mass \(2m\) placed at the centroid \(G\) of the triangle?
(Take \(AG=BG=CG=1\) m.)
1. \(Gm^2(\hat{i}+\hat{j})\)
2. \(Gm^2(\hat{i}-\hat{j})\)
3. zero
4. \(2Gm^2(\hat{i}+\hat{j})\)

1. \(Gm^{2} \left(\hat{i} + \hat{j}\right)\)
2. \(Gm^{2} \left(\hat{i} - \hat{j}\right)\)
3. 0
4. \(2Gm^{2} \hat{j}\)
