Class 11 Science Physics Gravitation

Two particles of equal mass go around a circle of radius R under the action of their mutual gravitational attraction. Find the speed of each particle.

(a)

v = \frac{1}{2 R} (\frac{1}{G m})

(b)

v = (\frac{G m}{2 R})

(c)

v = \frac{1}{2} (\frac{G m}{R})

(d)

v = (\frac{4 G m}{R})

Correct answer: (c)
