Physics, asked by manavmishra13, 4 months ago

Class XI students were given an experiment to find diameter of a wire using screw guage. The teacher

asked the student to take number of readings. Ravi took only three readings and finished his practical.

Seeing this, his friend Rahul asked him to take more readings as it would give more accuracy to his result

and also, they should follow the instruction of his teacher. If the diameter of the wire as measured by screw

guage was found to be 1.328,1.330,1.325,1.326,1.334 and 1.336cm.

i. Calculate mean value of diameter.

ii. Calculate absolute error in each measurement.

iii. Calculate relative error.

iv. Define a least count of the instrument

v. What is the need to take large number of readings in the experiment?​
