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.

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

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

Which is the correct answer? tell correctly.

Suraj said:   8 years ago
According to definition, only answer B is correct.

Staff intercept: is the difference between the reading measured at top cross hair and bottom cross hair of telescope.

Thanks @Aman and @Jeevitha.

Reading will increase in both cases, if tilted away or towards. Because it's minimum when staff held normal. So you can't go below the minimum. So answer D is also correct but B is more logical.

Staff intercept is the difference in reading between top and bottom cross hairs. If the staff is tilted forward or backward from normal, the staff intercept will increase. It is minimum when staff is truly vertical.
