Two particles 1 and 2 are allowed to descend on the two frictionless chord OA and OB of a vertical 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)
Text Solution
Verified by ExpertsThe correct answer is:
C
OA = d cos α α , a OA = g cos α α
⇒ ⇒ 
= 2gcos α α .d cos α α
= 2gd
= cos α α ,
Hence, is correct
