Question

If the measured value aap two quantities are a plus minus triangle A and B plus minus triangle b coma triangle and Angle B being the mean absolute error what is the maximum possible error in a plus minus b show that if Z equals to a upon B

Answer 1

Answer:

this is called Error in the product of 2 Quatities

Explanation:

consider the product

Z= AB

the error ♢Z in z is given by

Z +/- ♢Z = (A +/- ♢A) (B+/- B)

= AB +/- A♢B +/- B♢A +/- ♢A♢B

dividing lhs by Z and RHS by AB will get

1 +/- ♢Z/Z = 1+/-♢B/B +/- ♢A/A +/-♢A/A♢B/B

as♢A/ A and ♢B/B

are the small quantities their products can be neglected the maximum functional error in Z is

ur answer

♢Z/Z = ♢ A/A +♢ B/B

Hence the rule the maximum fractional error in the product of two quantities equal to the sum of fractional error in the individual quantities

plz like this so much mind used
