Step 1
It is given by: U = -G * (m1 * m2) / r where: - G is the gravitational constant (6.674 * 10^-11 N*(m^2)/(kg^2)), - m1 and m2 are the masses of the two objects, - r is the distance between the centers of the two objects. We have three pairs of masses here: (m1, Show more…

Three equal masses $m \mathrm{~kg}$ are placed at the vertices of an equilateral triangle of side $a$ metre. The gravitational potential energy equals to (A) $-\frac{3 G m^{2}}{a}$ (B) $-\frac{3 G m}{a^{2}}$ (C) $-\frac{3 G m}{a}$ (D) $\frac{3 G m^{2}}{a}$
