A student moves the mass to a distance d = 70.0 cm from the pivot. He adjusts the
height of the forcemeter until the rule is again horizontal. He records the reading F on
the forcemeter.
He repeats the procedure using d values of 60.0 cm, 50.0 cm, 40.0 cm, 30.0 cm, 20.0 cm
and 10.0 cm. The forcemeter readings are shown in Table 1.1
