A 30 m long steel tape standardized with a pull of 100 N was used to measuring a baseline of length 1800 m. While measuring the exerted pull was 150 N. The correction due to pull (Cp) is given by ________ (the area of cross section of the tape is A and Young’s modulus = E)
1
\(\frac{{50 \times 1800}}{{AE}}\)
2
\(\frac{{100 \times 1800}}{{AE}}\)
3
\(\frac{{150 \times 1800}}{{AE}}\)
4
\(\frac{{200 \times 1800}}{{AE}}\)
