Q. You measure two quantities as A = 1.0 m ± 0.2 m, B = 2.0 m ± 0.2 m. We should report correct value for √AB as:

1.4 m ± 0.4 m
1.41m ± 0.15 m
1.4m ± 0.3 m
1.4m ± 0.2 m

Answer: 1.4m ± 0.2 m

You measure two quantities as A = 1.0 m ± 0.2 m, B = 2.0 m ± 0.2 m. We should report correct value for √AB as
