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.
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.
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?

For positive errors, corrections will be negative and for negative errors, corrections will be positive.

Slope correction is always subtracitve.

Here is the relation b/w - error & correction.
CORRECTION = -(ERROR).
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.
