students attach a force probe in the middle of string a to measure ta and then use a different force probe to provide the applied force f to the box of mass m1. with the box of mass m3 held in place by one student, a second student pulls to the left on the force probe that provides the applied force f. as the second student pulls with a steady force, and with the boxes remaining at rest, the following pairs of readings from the two force probes are recorded at different times. Time F(N) TA (N) ti 10.6 11 10 10.4 10.2 10.8 10 11 t5 10.6 11 Based on the measurements above, how do the magnitudes of the two force quantities compare? The two quantities exactly agree numerically. The two quantities agree within experimental uncertainty but do not exactly agree numerically. The two quantities disagree by an amount that is larger than the experimental uncertainty. The two quantities cannot be compared because the two force probes have different levels of precision.
