JEE Main Physics question

In the determination of Young's modulus by using Searle's method, a wire of length and diameter is used. For a load , an extension in the length of the wire is observed. Quantities and are measured using a screw gauge and a micrometer respectively. They have the same pitch of . The number of divisions on their circular scale is 100. The contributions to the maximum probable error in the measurement **[IIT JEE 2012]**

• (A)Are due to the errors in the measurements of and , which are the sameCorrect
• (B)Are twice as much due to the error in as that due to the error in
• (C)Are twice as much due to the error in as that due to the error in
• (D)Are four times as much due to the error in as that due to the error in
