In an experiment on simple pendulum to determine the acceleration due to gravity, a student measures the elngth of the thread as 632 ~cm and diameter of the pendulum bob as 2.256 ~cm . The student should take the lenght of the pendulum to be

Options

  1. A64.328 ~cm
  2. B64.36 ~cm
  3. C65.456
  4. D65.5 ~cm

Correct answer

B. 64.36 ~cm

Step-by-step solution

length should be taken up to com array l _ net =63.2+ 2.256 2 64.328 array by signlicont figures _ net 64.3 ~cm
