Precision of MeasurementHardQuestion 30152

Question

A student uses a stopwatch with LC = 0.1 s to time 10 oscillations of a pendulum, getting 15.3 s. The time period is (15.3 ± ?) s. What is the error in the time period?
  1. A
    0.01 s
    Correct
  2. B
    0.1 s
  3. C
    1.0 s
  4. D
    0.03 s

Correct answer

0.01 s

Explanation

Error in total time = 0.1 s (LC). Time period T = 15.3/10 = 1.53 s. Error in T = 0.1/10 = 0.01 s.
