7. A student is holding a meter stick by one end. A 1000 g mass is hung on the meter sticks. All of the meter sticks
are identical, but the distance along the meter stick at which the 1000 g mass is hung and the angles at which the
student holds the meter stick vary. (Ignore the mass of the meter stick).

Rank these situations on the basis of how difficult it would be for the student to hold the meter stick from the left
end in the position shown.
