The main scale of vernier callipers has 10 equal divisions in 1 cm and 10 vernier scale divisions coincide with 9 main scale divisions, when both the jaws are in contact. Now, the above instrument is used to measure the external diameter of a cylinder. The 43rd division on the main scale is observed to the left of the zero of the vernier, when the object is held tightly in between the two jaws and the seventh division of the vernier coinsides with a division on the main scale, then

1.	The main scale of vernier callipers has 10 equal divisions in 1 cm and 10 vernier scale divisions coincide with 9 main scale divisions, when both the jaws are in contact. Now, the above instrument is used to measure the external diameter of a cylinder. The 43rd division on the main scale is observed to the left of the zero of the vernier, when the object is held tightly in between the two jaws and the seventh division of the vernier coinsides with a division on the main scale, then
Answer» The pitch of the SCALE is 0.1 cm The pitch of the scale is 0.01 cm The LEAST count of the APPARATUS is 0.01 cm The diameter of the CYLINDER is 4.37 cm Answer :B::C::D
