Sloping error is always positive and cumulative in nature.

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.

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.

Now we know that the given sloping distance is 15 meters and the elevation difference is 1.8 meters.
That means we know the slope i.e. H: V = 15 : 1.8.
But slope gives us the value of horizontal distance per unit error. We want an error per unit horizontal distance here means 1.8 : 15.
That gives us 0.12 which is cumulative of course due to slope. Hence it will be +0.12 cumulative or corrected for +0.11 cumulative.
