Question:medium
In a measurement, the random error
In a measurement, the random error
Show Hint
Random errors decrease with repeated measurements and averaging, while systematic errors require calibration or method correction.

- A screw gauge has a least count of $0.01$ mm. Using this screw gauge a measurement was done. When nothing was present in the jaw, zero of circular scale was above reference line by $3$ units. When a sphere was kept between the jaws, main scale reads $1$ mm and $51^{\text{st}$ division of circular scale coincides with reference line. Find the actual diameter of the ball:}
