A tall tower is built from alike tubes which have thin walls and from rectangular sheets which have negligible mass with respect to that of the tubes as shown in the figure rectangular sheets are numbered from bottom as S S S3 Static friction is big enough such that the tubes does not slip The radius of each tube is 1 cm 7 The minimum distance by which S should be pulled towards right so that the tower collapses is A 2cm C 4cm B 3cm D 5cm 20 cr cm
