When a screw gauge is completely closed, zero of circular scale is 4 division below the reference line of graduation. If least count of screw gauge is 0.001 cm, the zero correction is

When a screw gauge is completely closed, zero of circular scale is 6 divisions below the reference line of graduation. If least count of screw gauge is 0.001 cm , the zero correction is

While measuring diameter of a wire using a screw gauge the main scale reading is 7mm and zero of circular scale is 35 divisions above the reference line. If the screw gauge has a zero error of -0.003cm , the correct diameter of the wire is (given least count =0.001cm )

A student measured the diameter of a small steel ball using a screw gauge of least count 0.001 cm. The main scale reading is 5 mm and zero of circular scale division coincides with 25 divisions above the reference level. If screw gauge has a zero error of - 0.004 cm, the correct diameter of the ball is
