Question

The frequency of a tuning fork is found using f = n/t where n = 500 (exact count) and t = 10.0 ± 0.1 s. The %error in f is:
  1. A
    0.1%
  2. B
    1%
    Correct
  3. C
    0.5%
  4. D
    10%

Correct answer

1%

Explanation

Since n is exact (no error), %error in f = %error in t = (0.1/10.0)×100 = 1%.
