A brilliant student of Class `XII` constructed a vernier calipers as shown. He used two identical inclines of inclination `37^(@)` and tried to measure the length of line `AB`. The length of line `AB` is
.

_____ is used to measure the length of a curved line.

Will the lenghts of line segment AB and line segment BC make the length of line segment AC in Fig. 2.33 ?

Points A and B are on a circle of radius 5 and AB=6. Point C is the midpoint of the minor arc AB length of the line segement AC, is:

If line y = x - 8 meets y^(2) = 4x in A and B , then length of intercept AB is

The length of a cyclinder is measured as 5 cm using a vernier calipers of least count 0.1 mm. The percentage error in the measured length is nearly

Line segments AC and BD are diameters of the circle of radius one.If /_BDC=60^(0), the length of line segment AB is

Construct a line segment AB = 8.9 cm. Construct another segment AC such that C lies on AB and AC = 3.8 cm. Measure the length of the remaining line segment.

Consider a home made vernier scale as shown in the figure. In this diagram, we are interested in measuring the length of the line PQ. If both the inclined are indentical and their angles are equal to theta then what is the least count of the instrument.
