The notation of +_5 in measuring cylinders indicates the inherent error margin associated with the instrument's readings. Participants in the discussion emphasize that achieving a completely error-free instrument is impossible due to various factors affecting measurement accuracy. The conversation highlights the importance of understanding measurement precision and the limitations of graduated instruments in practical applications.

abi.ayan said:can anyone explain why is that noted?Most of them says that it denotes the error.why there should be an error in the instrument.Can't we make an instrument free of error?confused.
