A spherometer has a least count of 0.005 mm and its head scale is divided into 200 equal divisions. The distance between consecutive threads on the spherometer screw is :

A screw gauge has a least count of 0.005 mm and its head scale is divided into 200 equal division. The distance between consecutive threads on the screw is:

The least count of a screw gauge is 0.005mm and it has 100 equal divisions on its head scale. Then the distance between two consecutive threads on its screw is

Pitch of a screw gauze instrument is 0.5 mm and its circular scale is divided into 100 divisions. The least count of the instrument will be

1 mm of a main scale is divided into 10 equal divisions. The least count of the callipers is 0.005 cm, then the vernier scale must have

The pitch of a screw gauge is 0.5 mm and the head scale is divided in 100 parts. What is the least count of screw gauge ?

A screw gauge has least count of 0.01 mm and there are 50 divisions in its circular scale: The pitch of the screw gauge is:

A screw gauge has least count of 0.01 mm and there are 50 divisions in its circular scale: The pitch of the screw gauge is:

The meehanism behind nut and bolt arrangement also works for screw gauge. In case of nut and bolt mechanism, with rotation of bolt, it has translational movement also. In one complete rotation of bolt, tip of bolt moves by a linear distance equal to linear distance between two consecutive threads on the screw, known as pitch in case of screw gauge, the circular scale is divided in several parths. The ratio of pitch and total number of divisions on circular scale is known as least count. Spherometer is a device used to measure very small distances such as radius of curvature and thicness of thin plate. The screw gauge can be used to meaure diameter of a spherical sample. A screw gauge has 100 divisions on head scale and in 8 rotations distance covered is 8 mm. Least count of given screw gauge is
