Question

If the intercept on a vertical staff is observed as 0.5 m from a tacheometer, the horizontal distance between the tacheometer and the staff station is (assume K = 100, C = 0):

• A. 5 m
• B. 25 m
• C. 75 m
• D. 50 m

Hint:

Tacheometric rule: Distance = K × staff intercept (s)

Answer 1

The Correct Option is D

Tacheometric formula: \[ \text{Horizontal distance } D = K \cdot s + C \] Here:
- \( K = 100 \),
- \( C = 0 \),
- \( s = 0.5 \) m
\[ D = 100 \times 0.5 = 50 \, \text{m} \]
