If chain length is shorter than the original length then its +ive cumulative error in chaining. And if length of chain is longer than -ive cumulative error.

How to call the actual length if distance measured (300m)is given along with this same question?

What is the difference between cumulative and compensate?

If chain length is shorter than the original length then its -ve cumulative error in chaining. And if the length of the chain is longer then it's +ve cumulative error.

I think the answer should be B.

Please explain both cumulative and compensating.

The error in measured length due to the incorrect holding of the chain is a compensating error.
And negative errors are caused in the chain when its length is more than the standard length.
So the answer is C.
And negative errors are caused in the chain when its length is more than the standard length.
So the answer is C.

Kindly verify.
The error in chaining is -ve if the measured length is less than actual length.
Suppose, the actual distance is 30m.
And the chain is elongated by 1m.
The measured distance will be 29m.
The error will be 29 - 30= -1m.
i.e negative error.

Answer should be B. Because for negative error the measured length is less than actual length. And a cumulative error is proportional to L whereas compensating error is proportional to root L.

Compensating error removes self after completion of work or can say no effect on work.
