Which of the following statement(s) is/are correct?
I. A screw gauge having a smaller value of pitch has greater accuracy.
II. The least count of screw gauge is directly proportional to the number of divisions on circular scale.

View answer and explanation

Correct option: A

Only I

Option A (Only I) is correct because a screw gauge with a smaller pitch has greater accuracy, while the least count is inversely proportional to the number of divisions on the circular scale.

{\varepsilon _0}L\frac{{\Delta V}}{{\Delta t}},\;

{\varepsilon _0}

is the permittivity of free space, L is a length,

{\Delta V}

is a potential difference and

{\Delta t}

is a time interval. The dimensional formula for X is the same as that of
