Question

an experiment measures quantity a,b,c and x is calculated from formula x=ab1/2/c3/2 d3 the % error in a,b,c are 2%,4%6%and 1%respectively what is the%error in x​

Answer 1

Error in a,  aΔa×100=1%

Error in b  bΔb×100=3%

Error in c  cΔc×100=2%

The quantity is given as x=c3ab2

Error in measurement of x    xΔx×100=aΔa×100+ 2×bΔb×100 +3×cΔc×100

⟹  xΔx×100=1+2×3+3×2=13%

hope this helps you
