Analysis
The velocity values are for each corresponding voltage.
The centripetal force (experimental) values are averages for three measurements for each.

오차율 = | 2.7 – 2.563 N | / 2.7 N * 100 = 5.1 %
오차율 = | 4.5 – 4.351 N | / 4.5 N * 100 = 3.3 %
오차율 = | 6.6 – 6.506 N | / 6.6 N * 100 = 1.4 %
오차율 = | 8.8 – 8.898 N | / 8.8 N * 100 = 1.1 %

The theoretical values of the centripetal force with velocities 1.90 m/s2 and 2.45m/s2 do not lie within the range of the measured centripetal force values. However, it should be noted that the highest percentage of error was 5.1%, which allows for the conclusion that, in general, the experiment was fairly accurate.
