of least count 0.001 cm.He record the readings as

Observation

number

1 2 3 4 5 6

Observed

diameter D

(cm)

0.258 0.262 0.252 0.256 0.260 0.254

Now ,answer the following question
(a) What is the true value of diameter of given wire?

(b)Which of the observation is most accurate ?

(c) Calculate the mean value absolute errors in Gautam measurement ?

(d) What is the relative errors present in his measurement ?​

Answer 1

Answer:

True value = mean of the data=(0.258+; 0.262 + 0.252 + 0.2; .256+; 2.260 + 0.25 ) / 6 = 0.257 So, True .lue=0.257 cmMost |rate=1 and 4
