Track OABCD (as shown in figure ) is smooth. What minimum speed has to be given to a particle lying at point A, so that it can reach point C? (take g=10 m//s^2 )

Track OABCD (as shown in figure ) is smooth. What minimum speed has to be given to a particle lying at point A, so that it can reach point C? (take g=10 m//s^2 )

A particle is attached with a string of length l which is fixed at point O on an inclined plane what minimum velocity should be given to the particle along the incline so that it may complete a circle on inclined plane ( plane is smooth and initially particle was resting on the inclined plane . )
