Is any force exerted on the vertical sides of the loop that you used in the experiment and how does it affect the apparent mass? a. There is a force exerted on each side of the loop that are equal in magnitude and opposite in direction.
b. No force is exerted on the sides of the loop. The lengths of the sides of the loop are much smaller than the bottom section and therefore the force on the sides are negligible.
c. The force on the sides are not in the same direction in which the mass is measured and therefore it does not affect the results.
d. The force exerted on the sides of the loop cancel each other out.
