A rectangular block, with face lengths a = 35 cm and b = 45 cm, is to besuspended on a thin horizontal rod running through a narrow hole inthe block. The block is then to be set swinging about the rod like apendulum, through small angles so that it is in SHM. one possible position of the hole, at distance r from the block’scenter, along a line connecting the center with a corner. (a) Plot theperiod versus distance r along thatline such that the minimum in thecurve is apparent. (b) For what valueof r does that minimum occur? Thereis a line of points around the block’scenter for which the period of swinginghas the same minimum value. (c)What shape does that line make?
