The pressure on a square plate is measured by measuring the force on the plate and the length of the sides of the plate by using the formula `p=(F)/(l^(2))`. If the maximum errors in the measurment of force and length are `4%` and `2%` respectively. Then the maximum error in the measurment of pressure is

A

`1%`

B

`2%`

C

`8%`

D

`10%`

Text Solution

Verified by Experts

The correct Answer is:
C
`(DeltaP)/(P)xx100=(DeltaF)/(F)xx100+2(Deltal)/(l)xx100=4%+2xx2%`
`=8%`
