2b. [8 marks] Another student suggests that the relationship between t and h is of the form
t = k
where k is a constant.
To test whether or not the data support this relationship, a graph of t2 against 1/h is plotted
as shown below.
The best-fit line takes into account the uncertainties for all data points.

the answer is b, have negligible mass
