Question

The pressure on the square plate is measured by measuring the force on the plate and the length of the sides of the plate using formula p is equal to f upon l square is the maximum error in the measurement of force and length are 4% and 2% respectively then the maximum error in the measurement of pressure is

Answer 1

Answer:

the answer is 8%

Explanation:

pressure=force/area

area =l x l

l*2 =2x2=4%

FORCE=4%

force + area =8percent

remember errors are never subtracted...
