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.

The Correct answer is a positive commutative error.
Error =measured length - true length.
When the chain is too short ML >T. L.
SO, ERROR IS POSITIVE and it is commutative because every time we are using the same chain means we are adding.

The Length of a chain is short so the error will be negative and chain will also short for further measurements and error in only one direction so it will be a cumulative error so the answer is a negative cumulative error.

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.

Answer is C, because if the length of the chain gets short then we measured less value. Because noted down more value.
So, an error will be cumulative positive in nature and correction will be negative.
So, an error will be cumulative positive in nature and correction will be negative.

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.

The answer C is correct because it is a cumulative error not compensating. The error will increase in only one direction and it finally accumulates so it is compensating in nature.

Answer c is correct.
If the chain is short then we will have much reading and thus measured length minus actual length will be a positive value.
And thus the answer is correct.

Answer C is correct because they already declared that the tape is 30 m but the distance measured is less than the tape length by 0.01m. Hence it is positive cumulative error.
