Question

Measure of two quantities along with the precision of respective measuring instrument is :-
A= 2.5 m/s + 0.5 m/s
B = 0.10s + 0.01 s
The value of AB will be :-
(1) (0.25 +0.08)m
(2) (0.25 +0.5) m
(3) (0.25 +0.05) m
(4) (0.25 +0.135) m​

Answer 1

Measure of two quantities along with the precision of respective measuring instrument is A = 2.5 m s ± 0.5 ms B = 0.10 s ± 0.01 s The value of A B will be (a) (0.25 ± 0.08) m (b) (0.25 ± 0.5) m (c) (0.25 ± 0.05) m (d) (0.25 ± 0.135) m.

Answer 2

Answer - (1) 0.25 ± 0.08 m
