A vernier caliper has no zero error, one main scale division = 1 mm and 9 main scale division = 10 vernier scale divisions. A spring is held between jaws without exerting force on jaws. Main scale reading is 3.4 cm, and 5th vernier scale division coincides with a main scale division. When jaws are pressed by force of 10 N on both sides, main scale reading remains 3.4 cm, but 1st division of vernier scale coincides with a main scale division. Now spring is removed, cut into two pieces and when inserted between jaws without any force, main scale reading = 1.1 cm and 5th vernier scale division coincides with a main scale. If we apply force of 30 N on both the jaws, main scale reading gets 1.0 cm and x vernier scale division coincides with a main scale division. Find x.
