From length of square plate and force acting on it pressure on plate is measured. If error in force and length is 4% and 2% respectively, then maximum relative error in measurement of pressure will be …………..

A

0.01

B

0.02

C

0.06

D

0.08

Text Solution

Verified by Experts

`P=(F)/(A)`
For square plate `A=L^(2)`
`P=(F)/(L^(2))`
`:.` Percentage error in measurement of pressure,
`=deltaFxx100%+2deltaLxx100%`
`=4%+2xx2%`
`=4%+4%=8%`
