While measuring the length of a piece of a chalk by Vernier calipers. The main scale reading is found to be between 5.2 cm and the 5th division of a vernier scale is found to coincide with a division on the main scale. Find the length of the chalk if the least count of the vernier is 0.01 cm and zero error is 0.02 cm.
