In Searle's exp to find Young's modulus, the diameter of wire is mesured as `D=0.05cm` length of wire is `L=125cm`, and when a weight, `m=20.0 kg` is put, extension in wire was found to be `0.100cm`. Find maximum permissible percentage error in Young's modulus (`Y`)

In the experiment of Ohm's law, when potential difference of 10.0 V is applied, current measured is 1.00 A. If length of wire is found to be 10.0cm and diameter of wire 2.50 mm, then find maximum permissible percentage error in resistivity.

In the experiment of Ohm's law, when potential difference of 10.0 V is applied, current measured is 1.00 A. If length of wire is found to be 10.0cm and diameter of wire 2.50 mm, then find maximum permissible percentage error in resistivity.

Find stress required to double the length of a wire of Young's modulus Y.

If the least count of a screw gauge is 0.001 cm and diameter of a wire measured by it is 0.236 cm, find the permissible percentage error in the measurement.

In the Searle's method to determine the Young's modulus of a wire, a steel wire of length 156 cm and diameter 0.054 cm is taken as experimental wire. The average increase in length for 1 1/2 kg wt is found to be 0.050 cm. Then the Young's modulus of the wire.

In Searle's apparatus diameter of the wire was measured 0.05 cm by screw gauge of least count 0.001 cm. The length of wire was measured 110 cm by meter scale of least count 0.1 cm. An external load of 50 N was applied. The extension in length of wire was measured 0.125 cm by micrometer of least count 0.001 cm. Find the maximum possible error in measurement of Young's modulus.
