Problem

Four particles, each of mass

M

and equidistant from each other, move along a circle of radius

R

under the action of their mutual gravitational attraction. The speed of each particle is: (1)

\sqrt{\frac{GM}{R}}

(2)

\sqrt{2\sqrt{2} \frac{GM}{R}}

(3)

\sqrt{\frac{GM}{R}(1+2\sqrt{2})}

(4)

\frac{1}{2}\sqrt{\frac{GM}{R}(1+2\sqrt{2})}
