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

The Slop error is +ve.

Slope correction = h^2/2L = 1.8^2/(2*15) = 0.108~0.11.
Slope error is always + ive slope correction is always -ive.
So, Cumulative Error.

15- √(15^2-1.8^2) = 0.108 = .11.

AND we know slope correction is always negative so the error is positive 0.11.
Option A is correct.

Sloping error is always positive and cumulative in nature.

Error is positive.

And here we have to find an error. Therefore positive cumulative.

What is the difference b/w cumulative and compensating?

Siddhartha said:   8 years ago
For positive errors, corrections will be negative and for negative errors, corrections will be positive.

Harschle said:   8 years ago
Slope correction is always subtracitve.

Here is the relation b/w - error & correction.

CORRECTION = -(ERROR).

In this question, they are asking for error not correction so.

Correction is always negative.

But the error is positive.
That' s why the answer is +11.

As it is a systematic error not random error so it can be called cumulative error.
