Question

If the measured values of two quantities are A+- and ∆A andB+- ∆B, ∆A and ∆B being the mean absolute error what is maximum possible errorin A+-B?

Answer 1

Answer:

∆A + ∆B

Explanation:

If the measured values of two quantities are A+- and ∆A andB+- ∆B, ∆A and ∆B being the mean absolute error what is maximum possible errorin A+-B

A + B   Error   would be ∆A + ∆B

A - B   Error Would be ∆A + ∆B

maximum possible error in A± B  would be   ∆A + ∆B
