(b) Repeat the previous step for the column for the calculated centripetal force, but
this time instead of entering a ﬁxed value for the uncertainty, tell it to use the
column created in step 6
(c) Double click on the graph to bring up the graph options window and turn on the
option to show the x and y error bars and turn oﬀ the option to connect the data
points with lines.
