Find the minimum velocity required to send the ball to the top of this infinite structure....
Keep in mind:
The successive radius are half of the original ones.....
there are infintely many such.
The lowest loop has radius R, the 2nd R/2 , 3rd R/4 and so on...
The mass is of zero size
Velocity at the top is not zero in a single loop case! (So be careful when you are conserving energy!)

62Sorry wrong statemetn.. you can conserve energy.. but the velocity at the top is not zero :P
