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
- ABoth Statement-I and Statement-II are correct.
- BBoth Statement-I and Statement-II are incorrect.
- CStatement-I is correct & Statement-II is incorrect.
- 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 (\Rightarrow) finer linear movement per rotation (\Rightarrow) 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.
