Question

In an experiment to determine the value young,s modulus of elasticity of a steel wire using the formula Y=Mgl/πr²e the percentage error in the measurements of m,l,r and e were 2%,1%,2%,and1% respectively. Find the percentage error incurred in the measurement of Y

Answer 1

Might be 8℅ as g and π are constant so they won't account an error .. Keeping aside those constants the new equation becomes as
Y = Ml/r^2 e

So 2+1+4+1. Will give you 8℅

Answer 2

lots of effort to prove that
error of a quantity = sum of errors of directly proportional quantities - sum of errors of inversely proportional quantities

pls mark it as brainliest answer if possible
