eport 2. The second activity basically involves the torque due to the weight of the ruler versus the torque due to the weight of the coins. You observe that the more coins there are, the closer the coins need to be to the pivot point (i.e. the edge of the table) for the ruler to be on the verge of falling over. Why? a. The lever arm of the weight of the ruler needs to increase while the lever arm of the weight of the coins needs to decrease for the two torques to balance out.

You observe that the more coins there are, the closer the coins need to be to the pivot point (i.e. the edge of the table) for the ruler to be on the verge of falling over. Why?
a. The lever arm of the weight of the ruler needs to increase while the lever arm of the weight of the coins needs to decrease for the two torques to balance out.
b. The bigger the weight of the coins, the bigger the weight needed to balance it out; hence, more of the ruler needs to over the edge of the table.
c. The more coins there are, the bigger the normal force magnitude that needs to considered in determining the total torque of the system.
d. None of the choices
