Statement-I: A screw gauge having a smaller value of pitch has greater accuracy. Statement-II: The least count of screw gauge is directly proportional to the number of divisions on circular scale.

Options

  1. ABoth Statement-I and Statement-II are correct.
  2. BBoth Statement-I and Statement-II are incorrect.
  3. CStatement-I is correct & Statement-II is incorrect.
  4. DStatement-I is incorrect & Statement-II is correct.

Correct answer

C. Statement-I is correct & Statement-II is incorrect.

Step-by-step solution

- Statement-I: Smaller pitch ( ) finer linear movement per rotation ( ) higher accuracy. True. - Statement-II: Least count LC = pitch / number of circular-scale divisions. So LC is inversely (not directly) proportional to the number of divisions. False.
