Question If the length of rod \( \mathrm{A} \) is \( 3.25 \pm 0.01 \mathrm{~cm} \) and that of \( \mathrm{B} \) is \( 4.19 \pm 0.01 \mathrm{~cm} \) then the \( \operatorname{rod} \mathrm{B} \) is longer than \( \operatorname{rod} \mathrm{A} \) by
(A) \( 0.94 \pm 0.00 \mathrm{~cm} \)
(B) \( 0.94 \pm 0.01 \mathrm{~cm} \)
(C) \( 0.94 \pm 0.02 \mathrm{~cm} \)
(D) \( 0.94 \pm 0.005 \mathrm{~cm} \)📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
