1.	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 …………..
Answer» <P>0.01 0.02 0.06 0.08 Solution :`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%`
