In a particular scale A, one metreis divided into 500equal parts and in scale B one cm is divided into 5 equal parts and in scale C one mm is divided into 2 equal parts, then the accuracy of ` "________"`.A. (a)` A gt B gt C`B. (b) `A = B gt C`C. (c ) A = B gt C`D. (d)` A = B gt C`

Answer» Correct Answer - B
Last count of A= `1/500` = 0.002 " m ".
L.C of B = `(1cm)/5=(1xx10^(-2))/5=0.002 " m "`.
L.C of C= `(1 mm)/2=(1xx10^(_3))/2=0.0005 " g "m`.
So, " "L.C of A=B lt C. Then the accuracy of
A=B lt C.
