What is the reading of vernier scale shown in figure?

In a vernier calipers, N divisions of the main scale coincide with N + m divisions of the vernier scale. what is the value of m for which the instrument has minimum least count.

The least count of a vernier calipers 'X' is 0.01 cm. If the number of divisions on the vernier scale of another vernier calipers 'y' is double of that in 'X' , then the least count of 'Y' is _______ mm. (in both instruments 1 M.S.D. = 1mm)

The least count of a vernier calipers is 0.025 mm . If the 12th division of the vernier scale coinciles with a main scale division and the zero of the vernier scale is to the right of the zero of the main scale then the zero error is "______"

The least coun of a vernier calipers is 0.01 cm and if the zero mark of the vernier scale is right of zero of the main scale and the vernier coincidence is 7 when the jaws are in contact then the zero error is "_______" cm.

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 ________.
