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

Correction always negative but an error is positive.

h^2/2l = 1.8 * 1.8/15 * 2 =3.24/30 = 0.108 = 0.11.

Cumulative (systematic) error may b +'ve or -ve.

Correct answer is 0.108 but we take +0.11.

Slope correction is always subtracitve.

That is 1.8^2/(2*15) = 0.108~0.11.

Yes, option C is the right answer.

Same doubt for me. How 1.08 =.11?

h2/21 = 1.8^2/(2*15) = 1.08~.11.

The systematic error means?
