A force F is applied in a square plate of length L . If the percentage error in the determination of L is 3% and in F in 4% then permissible error in the calculation of pressure is

A

0.13

B

0.1

C

0.07

D

0.12

Text Solution

Verified by Experts

The correct Answer is:
B
Answer (2)
Pressure, `P = F/A = F/L^2`
Permissible error
`(DeltaP)/P "times" 100 (DeltaF)/F xx 100 + 2 (DeltaL)/L xx 100`
4% + 2(3%)
= 10%
