CORRECTION in one question (SUBJECT:- VIBRATION)

In the question paper (AG-09),there is a question related to relation between QUALITY FACTOR and DAMPING RATIO.In that question DAMPING RATIO is given and we need to find the QUALITY FACTOR, by mistake we used the formula


QUALITY FACTOR = 1/(DAMPING RATIO)
but the correct formula is

QUALITY FACTOR = 1/(2 x DAMPING RATIO)

please check the question papers and correct it.
