The main scale reading is 1 cm, the Vernier coincidence is 5, and the negative zero error is 0.02 cm. Calculate the correct reading.
The main scale reading is 8 cm and vernier coincidence is 4 and negative zero error is 0.02 cm. Then calculate the correct reading: [2marks]
the least count of a vernier calliper is 0.01 cm and it has an error of +0.07 cm . While measuring the radius of a sphere , the main scale reading is 2.90cm and the 5th vernier scale div. coincides with main scale . Calculate the correct radius.
