Which is the correct unit for measuring nuclear radii

Student I, II and III perform an experiment for measuring the acceleration due to gravity (g) using a simple pendulum. They use different lengths of the pendulum and/or record time for different number of oscillations. The observations are shown in the table
Least count for length = 0.1 cm.
Least count for time = 0.1 s.

If E_I,E_II and E_III are the percentage errors in g, for students I, II and III respectively.
