Answer» A micrometer has 150 equal divisions on the circular scale, and on ONE FULL rotation of circular scale main scale advances by 0.02 cm on the main scale. To FInd : The least count of the micrometer (in cm) isSolution: micrometer has 150 equal divisions on the circular scale, and on one full rotation of circular scale main scale advances by 0.02 cm on the main scale.1 main Scale = 150 Vernier scale Divisions1 main Scale = 0.02 cm150 Divisions = 0.02 cm=> 1 Vernier scale Divisions = 0.02/150 cm=> 1 Vernier scale Divisions = 2/15000 cm=> 1 Vernier scale Divisions = 2/(1.5 X 10⁴) cm=> 1 Vernier scale Divisions = 1.33 x 10⁻⁴ cm The least count of the micrometer (in cm) is 1.33 x 10⁻⁴ cmLearn More:if a voltmeter shows 5 DIVISION deflection and its least count is 0.1 ... brainly.in/question/11111083The least count of a SCREW gauge is 0.005 cm.
