For each natural number K, let Ck denote the circle with radius k centimeters and centre at the origin. On the circle Ck , a particle moves k centimeters in the counter clockwise direction. After completing its motion on Ck, the particle moves to Ck+1 in the radial direction. The motion of the particles inthis manner. The particle starts at (1,0).
If the particle crosses the +ve direction of x axis for the first time on the circle Cn, Find n!
