A physical quantity is represented by `X=M^(a)L^(b)T^(-c)`.If the percentage error in the measurement of M,L and T are `alpha%, beta%` and `gamma%` to respectively, what is the total percentage error in X?

A

`a" "alpha+b" "beta+c" "gamma`

B

`a" "alpha+b" "beta-c" "gamma`

C

`(a)/(alpha)+(b)/(beta)+(c)/(gamma)`

D

None of these

Text Solution

The correct Answer is:
A
`X=["M"^(a)"L"^(b)"T"^(c)]`
Maximum % error in `X=a" "alpha+b" "beta+c" "gamma`
