Solution
The correct option is B1/(√2−1)
angular velocity of the particle is 2πT=2π8=π4
in first sec it move at a angle π4
if we take a projection of circular path on the axis of is 1√2
in another second sec it move at a another π4
it distance at the axis 1−1√2
ratio of distance in first second and in 2 second 1√21−1√2
