Two identical particles of mass 1 kg each go round a circle of radius R , under the action of their mutual gravitational attraction. The angular speed of each particle is:

Options

  1. AG 2 R 3
  2. B1 2 G R 3
  3. C1 2 R 1 G
  4. D2 G R 3

Correct answer

B. 1 2 G R 3

Step-by-step solution

F = G m 2 ( 2 R ) 2 = m R ω 2 ω = 1 2 G R 3
