Find:

• (i) The true R.L. of B
• (ii) Combined corrections for curvature and refraction and Error in collimation adjustment of the instrument.

2(b) Write a detailed note on obstacles in chain surveying.

2(c) A line was measured with steel tape which was exactly 30m at a pull of 5kg and measured length was 229.62m. The pull applied during measurement was 10kg and the tape was uniformly supported.
