Vernier Caliper

There are two Vernier calipers both of which have 1cm divided into 10 equal divisions on the main scale. The vernier scale of the calipers ( c_(1)) has 10 equal divisions that correspond to 9 main scale divisions. The Vernier scale of the other calipers ( C_(2)) has 10 equal divisions that correspond to 11 main scale divisions. the reading of the two calipers are shown in the figure. the measured values (in cm) by calipers C_(1) and C_(2) respectively, are

Reading A Vernier Calliper

A vernier calipers and a screw gauge have the same least count and zero error with the difference that the vernier calipers has positive zero error and the screw gauge has negative zero error. The number of circular scale divisions on the screw gauge is twice the number of vernier scale divisions on the vernier calipers and the pitch of the screw gauge is 1mm. If the vernier coinciding division and the circular are 3 and 97, respectively then find the number of vernier scale divisions on the vernier calipers.

While measuring the diameter of a sphere using a vernier calipers the main scale reading was found to be p while the vernier coinciding division was q. If the least count of the instrument is r, then the radius of the sphere is given by the expression ________.

The smallest division on the main scale of a vernier calipers is 0.1cm. Ten divisions of the vernier scale correspond to nine divisions of the main scale. The figure below on the left shows the reading of this calipers with no gap between in two jaws. The figure on the right shows the reading with a solid sphere held between the jaws. The correct diameter of the sphere is.

The length of a rectangular plate is measured by a meter scale and is found to be 10.0 cm . Its width is measured by vernier callipers as 1.00 cm . The least count of the meter scale and vernier calipers are 0.1 cm and 0.01 cm respectively. Maximum permissibe error in area measurement is.
