The pressure on a square plate is measured by measureing the force on the plate and the percentage error of measurement of force and length are respectively 4% and 2%, the maximum error in the measurement of pressure is-

A

0.01

B

0.02

C

0.06

D

0.08

Text Solution

Verified by Experts

`P=(F)/(A)=(F)/(L^(2))`
For max. error
`(DeltaP)/(P)=(DeltaF)/(F)+(2DeltaL)/(L)=4%+2(2%)=8%`
