Question

If two quantities a and b having absolute error ∆a and
∆b respectively are added, then absolute error of result
will be equal to:-

a. (∆a + ∆b)
b. (∆а - ∆b)
c. (∆a/a + ∆b/b)
d. (∆a/a - ∆b/b)​

Answer 1

Answer:

∆a+∆b

If quantities are added or substracted, absolute uncertainties are always added
