• ( 3 ) Pick up the incorrect statement from the following :

• 1) a 100 m tape of cross section 10 mm x 0.25 mm stretches about 10 mm under 5 kg pull.
• 2) while measuring a distance with a tape of length 100.005 m, the distance to be increasing by 0.005 m for each tape length
• 3) an increase in temperature causes a tape to increase in length and the measured distance is too large
• 4) the straight distance between end points of a suspended tape is reduced by an amount called the sag correction
