The magnitude of ‘sag correction’ during measurement of lengths by taping is proportional to the :
(a) Cube of the weight of the tape, in kg per m run
(b) Cube root of the weight of the tape, in kg per m run
(c) Square of the weight of the tape, in kg per m run
(d) Square root of the weight of the tape, in kg per m run
