1.	A particle is moving along a circular track of radius 1m with uniform speed. What is the ratio of the distance covered and the displacement in half revolution?
Answer» SOLUTION :Distance covered by a particle `= pi xx 1 = pi m` DISPLACEMENT covered by a particle `= 2 xx 1` = 2 m Ratio between distance and displacement = `pi/2`
