JEE MainPhysicsGravitationMCQ+4 / −1
Four particles, each of mass MMM and equidistant from each other, move along a circle of radius RRR under the action of their mutual gravitational attraction. The speed of each particle is :
  1. A
    GMR\sqrt {{{GM} \over R}}RGM​​
  2. B
    22GMR\sqrt {2\sqrt 2 {{GM} \over R}}22​RGM​​
  3. C
    GMR(1+22)\sqrt {{{GM} \over R}\left( {1 + 2\sqrt 2 } \right)}RGM​(1+22​)​
  4. D
    12GMR(1+22){1 \over 2}\sqrt {{{GM} \over R}\left( {1 + 2\sqrt 2 } \right)}21​RGM​(1+22​)​
