Two blocks of masses ‘m‘ and '2m' connected by a massless string move along concentric horizontal circles on a horizontal frictionless table with 'O' as fixed point as shown in the figure. If ‘T’ is the period of motion, the tension in the longer part of the string is
(Neglect the dimensions of the blocks when compared with the lengths of the string).
