1.	Two particles 1 and 2 are allowed to descend on the two frictionless chord OA and OB of a vetical circle , at the same instant from point O. The ratio of the velocities of the particles 1 and 2 respectively , when they reach on the circumference will be (OB is the diameter)
Answer» Solution :`OA= d cos alpha _(OA)=G cos alpha ` ALONG OA `rArrV_(A)^(2)=2g cos alpha . D cos alpha ` Along OB `V_(B)^(2) =2gdrArr (V_(A))/(V_(B))= cos alpha`
