1.	A particle of mass m is suspended from the ceiling through a string of length L. The particle moves in a horizontal circle of radius r. The speed of the particle is
Answer» `(rg)/(sqrt(L^(2)-R^(2)))` `(rsqrtg)/((L^(2)-r^(2))^((1)/(4)))` `(rsqrtg)/((L^(2)-r^(2))^((1)/(2)))` `(MGL)/((L^(2)-r^(2))^((1)/(2)))` Solution :`(F)/(r )=(mg)/(sqrt(L^(2)-r^(2)))`
