10.
A uniform slope was measured by the method of stepping. If the difference in level between two points is 1.8 m and the slope distance between them is 15 m, the error is approximately equal to
cumulative, + 0.11 m
compensating, ± 0.11 m
cumulative, - 0.11 m
none of these

Your are right @Satya.

@Saurabh.

An error that increases with the size of the sample revealing it.

Saurabh. said:   9 years ago
What is cumulative?

Satya said:   9 years ago
h^2/2l = 1.8 * 1.8/15 * 2 =3.24/30 = 0.108 = 0.11.

Birbal said:   9 years ago
Correct answer is 0.108 but we take +0.11.

Jwala said:   9 years ago
Correction always negative but an error is positive.

Apcivil said:   9 years ago
Yes, option C is the right answer.

SOUVIK said:   9 years ago
I think the answer is [C].cumulative, - 0.11 m; because slope correction is always negative. plz, anyone describes it .

Yogii said:   9 years ago
0.108 only coming ~.11 in slope error is only cumulative +0.11.

G.K said:   9 years ago
Error due to slope correction is always +ve so from option it's +0.11.
