Two particles 1 and 2 are allowed to descend on two frictionless chords

OP and OQ. The ratio of the speeds of the particles 1 and 2 respectivelywhen they reach on the circumference is:

Answered by admin @ 17/08/2021

Explanation:

Let radius of circle = R

Oq=Pq=R, So △OPq is a equilateral triangle

So Particle on chord OP will travel vertical distance = Rcos60=

∴ From work-energy theorem mg(R/2)=

⟹v

Particle on chord OQ will travel vertical distance = 2R

Similarly for particle on OQ- v
