If a physical quantity X is represented by X=M^(a)L^(b)T^(-c) and the % error in M,L and T are alpha%, beta% and gamma% resperctively, then total % error in X is : |
|
Answer» `(alphaa+betab-gammac)%` `:. (DeltaX)/(X)xx100` `=a((DeltaM)/(M)xx100)+b((DeltaL)/(L)xx100)+c((DeltaT)/(T)xx100)` `=(alphaa+betab+gammac)%` So the correct CHOICE is `(b)`. |
