Question

. When the length of chain used in measuring distance is longer than the standard length, the
error in measured distance will be
(a) positive error
(b) negative error
(c) compensating enor
(d) none of these​

Answer 1

Answer:

The error in measured distance will be the negative error.

Answer 2

The error in measured distance will be negative error.

Option: (b)

Explanation:

• When the length of the chain used in measuring distance is longer than the standard length, the error in measured distance will be negative error because the chain will measure a larger distance than the original distance.  

• This extra distance measured by the longer chain has to be subtracted from the original length.  

• Hence the error will be a negative error and not a positive error.  

• Since a series of lengths are not being measured it is neither compensating nor cumulative error.
