1.	Four particles each of mass 'm' are located at the four corners of a square of side 'a'. If the the system is revolving in a uniform circle due to there is mutual force if attraction, then the angular velocity of each particle is
Answer» `SQRT((GM(2sqrt(2)+1))/(a^3))` `sqrt((Gm)/(a^3)(sqrt(2)+1))` `sqrt((Gm)/(a^3)(sqrt(2)+(1)/(2)))` `sqrt((Gm)/(a^3)(2+(1)/(sqrt(2))))` ANSWER :D
