In a vernier callipers, each cm on the main scale is divided into 20 equal parts. If tenth vernier scale division coincides with nineth main scale division. Then the value of vernier constant will be _____ × 10 - 2 mm

Correct answer

0

Step-by-step solution

Vernier constant is defined as the difference between the value of one main scale division and one vernier scale division. It is also known as the least count of vernier calliper. The main scale division of the given vernier calliper is M S D = 1   cm 20 = 0 . 5   mm . L C = M S D n = 0 . 5   mm 10 = 0 . 05   mm = 5 × 10 - 2   mm
