Which is the correct answer? tell correctly.

Since, staff is held inclined, cross hairs will intercept more readings than that of a vertically held staff in vertical direction.

I think in both condition, value increase if staff tilted.

If the staff is tilted away from the instrument intercept will be more n if staff is tilted towards the instrument the staff intercept will be minimum.

Good explanations, thank you all.

How to define interception?

Jwala said:   7 years ago
If the staff is tilted away I think value increase. Just visualise a staff with the inclination and straight.

If staff is tilted then what is the answer?

Ravi kumar said:   8 years ago
Answer B is right. Think again and visualise a laser beam as a line of sight and a objects going away from normal. The reading will increase as it starts from zero at bottom and max st top.

That's a wrong answer.

It must lie at the center of the telescope.
