Answer:
Explanation:
a ) Let breadth be L , then length will be 1.5 L
Since it is a meter scale , the least count is 1 m.m. So
maximum possible error in a measurement is 1 mm.
In both the measurement of length and breadth , absolute
uncertainty will be 1mm.
Hence there is no difference in absolute uncertainty of their measurement.
b ) percent uncertainty in the measurement of length
= 1 / 15L%
percent uncertainty in the measurement of breadth
1 / 10L%
In breadth it will be higher by
( 1/10L - 1/15L)/ 1/10L
= 1/3
c ) Uncertainty in the measurement of R= 1 %
Area A = π R²
ΔA/A X100 = 2 X ΔR/R X 100
Percentage uncertainty in A = 2 X percentage uncertainty in R
= 2 X 1
=2 %
Therefore percentage accuracy in the calculation of area
= 2 %.
