instrument. All measuring instruments used in physics have a least count. A meter ruler’s least count is 0.1 centimeter; an electronic scale has a least count of 0.001g‚ although this may vary; a vernier caliper has a least count of 0.02 millimeters‚ although this too may vary; and micrometer screwgauge’s least count is 0.01 millimeter and of course a conventional ruler has .01m. The Least Count is the discrimination of a vernier instrument. All measuring instruments used in the subject of physics

were fixed on ceiling of lab on one end and other end had vernier caliper like measurement device. My controlled variable was the diameter of Wire‚ Length of wire and acceleration due to gravity (g = 9.8 ms-2) and independent variable was the load that can be applied to the string‚ which were given in the form of 0.5 kg blocks and had constant mass. Extension of string was the dependent variable and it was measured with a vernier caliper with the accuracy of 0.001mm. The equation of Young modulus
