JEE MainPhysicsGravitationMCQ+4 / −1
Four identical particles of equal masses 1 kg made to move along the circumference of a circle of radius 1 m under the action of their own mutual gravitational attraction. The speed of each particle will be :
  1. A
    G2(1+22)\sqrt {{G \over 2}(1 + 2\sqrt 2 )}2G​(1+22​)​
  2. B
    G2(22−1)\sqrt {{G \over 2}(2\sqrt 2 - 1)}2G​(22​−1)​
  3. C
    G(1+22)\sqrt {G(1 + 2\sqrt 2 )}G(1+22​)​
  4. D
    12G(1+22){1\over2}\sqrt {G(1 + 2\sqrt 2 )}21​G(1+22​)​
