A physical quantity `rho` is related to four variables `alpha, beta, gamma` and `eta` as
`rho=((alpha^3)(beta^2))/(etasqrt( gamma))`
The percentage errors of measurements in `alpha, beta, gamma` and `eta` are `1%, 3%, 4%` and `2%` respectively. Find the percentage error in `rho`.

Text Solution

Verified by Experts

The correct Answer is:
A, C
`%` error in `rho = 3` (`%`error in `alpha`) `+ 2` (`%` error in `beta`)
`+1/2` (`%` error in gamma) `+` (`%` error in `eta`)
