The hook of each bal-ance is to be attached by aloop to the meter other end of each bal-ance is to be clamped to Fi 32the edge of the table op-posite the meter stick. These two balances are to beclamped so that they make acute angles with the meterstick and, if possible, these angles should be different, asshown in Fig. 31. Perpendicular distances may be measured by using atriangle and a half meter stick, as shown in Fig. 32. Make the following readings and record in tabular formnear the top of the left-hand page of note-book. Observations Reading of balance A g, Heading of balance B ....... g Point of application of force A cm Point of application of force B cm Position of fulcrum on meter stick .... cm Perpendicular dista
