Two identical particles each of mass m go round a circle of radius a under the action of their mutual gravitational attraction. The angular speed of each particle will be:
Text Solution
Verified by ExpertsThe correct answer is:
C
The gravitational force (F G ) between the particles is given by
...
The centripetal force (F c ) of each particle can be written as
F c = m 
2 a ...
Under balanced condition, equate equation and equation and simplify to obtain the angular speed of each particle.
