A student measured the diameter of a wire using a screw gauge with the least count 0.001 ~cm and listed the measurements. The measured value should be recorded as

Options

  1. A5.3200 ~cm
  2. B5.3 ~cm
  3. C5.32 ~cm
  4. D5.320 ~cm

Correct answer

D. 5.320 ~cm

Step-by-step solution

The least count (L.C.) of a screw guage is the smallest length which can be measured accurately with it. As least count is 0.001 ~cm = 1 1000 ~cm Hence measured value should be recorded upto 3 decimal places i.e., 5.320 ~cm
